Hi Craig,
Great looking car and a terrific set-up to work on it!
Regards,

First real use for the Quickjack.

Need to swap the Borgeson steering box, so header needs to come off to give some clearance.

All out in no time and a lot simpler than in the past.

CraigH

Before fitting the new Borgeson box wondered if anyone had experience Tyre rubbing on the steering box bolt heads.

They supply normal hex head bolts when the stock ones were carriage bolts.

I used stock bolts with first Borgeson box but needed a few washers as they were a bit longer than needed and thread did not go down far enough.

May just go to the local fastener shop and try and get carriage ones correct length.

Clean......and very good pics!

NO issues with tire rub, but I am running stock size Tires on factory rims. Size : 225 - 70 - 15's.

CraigH

Thanks....

Now the floor is painted i find myself wiping up all the dirt or fluids that drop when you do any work. Previously they stained the floor but now just wipe off the paint.

I like taking lots of pictures as ......

1) it helps me remember what i have done, so next time i have to do it i can quickly review and get going without having to make the same mistakes over :-)

2) it may help others that may need to do the same thing. (Lots of other posts here have certainly helped me)


Re the bolts I may look for grade 5 round headed carriage bolts as the last thing i want is to damage a tyre on full lock.

CraigH

I am actually thinking about putting my 215/70/15 white stripe set back on for a while after i get all the steering down, aligned etc.

Love the large wheels but have a soft spot for the originals as well.

BLUE1972

I put the 215 size under the car while on the lift, they looked too small, the 225 looked better. Their size is close to original.

The 215 to me just looked to small, from the rear. The F70 I have, which is original spare is about the same with as the 225. I would guess there is a difference in the dimension's with different manufacturers. as I measured my stock F70 against my friends and there is a 1/2 " difference -

CraigH

That interesting. I always thought the 215/70/15 had the correct rolling diameter to match the old style tyres.

So it may be the 215 is the correct height but 225 is closer in width.

CraigH

I have been sourcing all the bits i need to finish putting in the replacement Borgeson box and I was a bit fixated on the bolts



1 is the stick bolt with a carriage head. Grade 5.
2 is the bolts that came with my Borgeson in 2010. Grade 5.
3 is the bolts that came with my newest Borgeson box. Grade 5.
4 is all i could get here in Australia with a carriage head. Grade 2 :-(

But luckily I found great place on line in the US called the BoltDepot

http://www.boltdepot.com

They had both Grade 5 and Grade 8 carriage head bolts in 4" and all the bits i needed so a quick order and its on its way to California where i will pick it up in a few weeks when i am over for work.

Now no concerns of the tyres rubbing on the bolt heads

Also noticed that my Pitman arm looks a bit sad in its threads so have sourced another on eBay and its on its way as well.

This explains why it would not go on fully last time.

BLUE1972

For bolts did you try a MARINE SUPPLY house, they also have Stainless Steel in structural bolts. If there is a local boat builder he may have all the parts you need.

I have also used a Tractor trailer repair / builder for strange parts / bolts.

Hope this may help.

CraigH

Ahh similar thoughts....

The local specialty fastener shop only had the Grade 2 carriage bolts but recommended I go to the local Tractor replacement parts place as he thought they had them.

They did but not 4".

Not a lot of marine places near where i am but I did ring number of specialty bolt paces in Sydney and Melbourne and all had a big no.

In the end http://www.boltdepot.com came through :-)

riverracer au

since we don't get to see you much on the local Oz forum anymore,
and i have to catch up with your updates here,

will you be going to Bendigo for the convention at easter time?

CraigH

Hi Alan

yes I stopped updating the thread on the Australian site and just do this one.

Not registered for the Bendigo Convention but dependant on other travel etc i may drive down to have a look anyway.

Metalhead140

Will they ship to Aus? I'm still using the original bolts with my Borgeson for the same reason.

CraigH

Probably, I did not even check that just used my US freight forwarder address at shipito.com.

I will pick them up from there when i am in the US next week.

Once i get them and get back i will fit it up and ensure they do the job as expected.

If it turns out they won't ship to Australia PM me and I can add some to a future package i get shipped over.

Not sure when that will be but there seems to be one every 3-4 months based on history :-).

Metalhead140

Thanks! Let me know if all is well when you get them home. I've ordered the ridetech steering box brace also, as the chassis flex is (to me) quite alarming around the steering box, but I intend to modify the holes in the brace (which are round) to take the standard carriage style bolts. I do polish the bolt heads at full lock, so don't think hex heads are a good idea for me...

n8dogg

I will be referencing to this thread while I further improve my 72!

very nice

BLUE1972

a supplier for hardware nuts and bolts is :

http://www.mcmaster.com/#

they have grade 5 and grade 8. Don't know if they ship out of the US, buy probably will.




No. 3 Square Neck with Flat Head—Bolts are zinc-plated Grade 5 medium-strength steel. The top of the head is marked with three radial lines to indicate Grade 5. Minimum tensile strength is 120,000 psi. Minimum Rockwell hardness is C25. Dimensions meet ASME B18.9.

No. 3 Square Neck with Dome Head—Bolts are zinc-plated Grade 8 high-strength steel. The top of the head is marked with six radial lines to indicate Grade 8. Minimum tensile strength is 150,000 psi. Minimum Rockwell hardness is C33.

Carriage Bolts
Square Neck

The neck shape keeps these bolts from turning when tightening a nut. The bolts have a smooth, rounded head. Length is measured from under the head. Stainless steel and galvanized steel bolts are a good choice for ACQ-treated (arsenic-free) lumber. Inch sizes have a Class 2A thread fit. Inch size square-neck bolts meet ANSI B18-5. Metric sizes have a Class 6g thread fit, except M6 bolts have a Class 8g thread fit.

Type 316 Stainless Steel—These are our most corrosion resistant carriage bolts.

18-8 Stainless Steel—More corrosion resistant than zinc-plated and hot-dipped galvanized steel bolts.

Zinc-Plated Steel—Offer good corrosion resistance. Medium-strength steel (Grade 5) meets SAE J429. Low-strength steel (Grade 2) meets ASTM A307 or SAE J429.

Hot-Dipped Galvanized Steel—These low-strength (Grade 2) steel bolts are more corrosion resistant than zinc-plated steel bolts. They meet ASTM A307; galvanization meets ASTM 153. Bolts must be used with hot-dipped galvanized nuts.

Bronze—These bolts are corrosion resistant and stand up to salt water. They are not rated for hardness.
