Default 63 A/C Roadster “Yard Find” Number Decoding

Hello, Well please see the other post to get the initial story.

http://forums.corvetteforum.com/c1-a...a-c-value.html

In an effort to authenticate the car completely I have been going thru the numbers to confirm its true originality. So far I really don’t find much that has been changed or modified of the main components on the car. Below I have outlined a list and would like to hear any comments or even point me further on any other important items I haven’t checked. I am also trying to put together an album to post pictures somehow as I have hundreds of them to document and it keeps growing. The car has 74k original miles.

Trim Tag
Build Date I5 = 5th week of May 1963
Style 63 867 7897 Body
Trim 490XH (drk blue vinyl) | 912A PAINT (silver blue paint with white top)

Motor Deck Stamp – F0522SD
Intake Date – D 26 3
Alternator - 1100665 – 55 A – 3M12 12V NEG - From my readings this shows for a 64??
Distributor Tag – 3 C 18
Starter - 1107242 J29 - Is this October 29th?
Carburetor – 3826006 / 3460S
Air Compressor – Mod 6550133 - 63NC1591
Radiator – Harrison 3155316 63E
Radiator Remote Tank - Harrison 3155416 63E
Water Pump - I 10 3
Thermostat housing – 3827369 B3

Rear Housing - 3830308 GM3
Axle Stamp – CA 5 17 63
Transmission Pan Stamp – T05 22D

Side Glass - Soft Ray LOF XC
Windshield – Shaded E-Z EYE

I have not checked the brake booster or master cylinder but the master has a bleeder screw on it. Where are the numbers located on these?

When going through the parts I also found a 4 hole attachment Luggage Rack and under further investigation I found some filled holes in the deck.. From what I understand this was a dealer installed item and wonder how to tell it is a true GM part?

Thanks again and look forward to this new venture and any input you guys can give.. I always wanted an older Corvette to restore but never thought I would end up with one of this Rarity. I was told that this may be one of less than 48 Convertibles built and wonder how many are in existence. I guess there is finally an excuse to join the NCRS!

Dave, Some info from my 63-64 judging guide.....

The Starter pt# is correct. Date J29 is Sept 29. No "I" for stamped Delco electrical items. Starter appears replaced.

Alternator s/b 1100633 w/AC, 52A. 1100665 is correct 55A for '64 w/AC.

The AC compressor is correct part#, 6550133. The 6xNC1591 is the serial #. Check again it is likely 68NC, not 63NC.
The date code will be in the rear plate, raised chars. MDDY format.

The PB master cylinder numbers are on the bottom. Casting # s/b 5462389. DC MDDY format, with bleeder screw on originals. Cover should use a thumbscrew for early cars, later used hex bolt. I recall the master on the car had a bail on the cover, which is 1964 style, pt# 5464264.

The PB booster is 5462025. The "2025" is stamped at the tabs where the 2 halves join, at 10 & 4 o'clock positions.

A few other #'s to look for are exhaust manifolds, but will likely be hard to read if rusted. Also the carb will have a date stamp on the pass side front base. The engine cast date? Near dist rear of block.

all for now....Rich

Thanks Rich.. Your right about the 68NC on the compressor and I will check for the date code later tonight. Looks like the MC has been changed as well and I was reading the the bolt top was used on Power Brake cars instead of the thumb screw to clear the hood?

Congratulations, you got a great car. I'll ask the big question that everybody would like to ask but may be reluctant...the owner wanted $50. How would you describe the actual sale price? Dennis

Took the radiator out tonight to flush it all out and after removing the hoses and throwing them on the floor I noticed a GM stamp on the Lower hose.. So I picked up both and this is what I seen. Is it possible they are the originals or did they make repops in the late 70's?







Thanks Dave

Found some factory markings:

What I believe to be PG on the passenger side bottom floor? Maybe stands for powerglide?



E 211 on the passenger door shell.. What would that indicate May 21st?

Brake Booster has a Stamp of 2574 on one tab but could not find the date code.. Is it on the back of the 2574 like my Chevelle Booster stamps are?

Found the date code on the compressor and numbers read 6553302 with a 13 underneath and date code of C 4 3 (March 4th)

Also has a neat "OK FINAL TEST" CHEV Stamp.

Then that is what the "E" is on your door The number 211 is the build number. You should find that number on the pass side of the lower firewall on the other door behind the dash cluster on the bird cage and on the rear bulk head in front of the gas tank

Since the car has been off the road since 1980, it's quite possible they're original, particularly since it's the original radiator. If the "4K03A" is a datecode, questionable.

The lower hose I took off our 63 coupe a few years ago, with it's original radiator appeared to me to be original also. I have it saved in a box. I'll have to check the numbers on it.

p.s. Nice garage!

Can you post a picture showing the location og the voltage regulator and horn relay?
Looking at the assembly manual it shows the horn relay on the radiator support and the voltage regulator on the left inner fender

On my 64 coupe both the voltage regulator and horn relay is placed on the left side radiator support

Those hoses were still available from Chevrolet, as recently as 5 years ago. So they're very likely old GM hoses, but not necessarily the hoses delivered on the car.

As far as I know, GM may still stock the hoses. The only reason I stopped buying GM ones, was because the markings on the repros are correct, while the markings on the GM hoses weren't any more.

It's hard to make out the part number, on the upper hose. Can you tell what it is? It appears that it could be either 3827366 or 3827368. The 368 is the correct upper hose for an AC car, 366 is for 250 or 300 without AC.

I believe that is correct. Our early '64 powerglide car is marked similarly just below the job number:

How did you determine that the A meant it had a white top? I have looked everywhere to verify this and couldn't find a dependable resource. Great find btw.

I don't think the OP is going to get back to you on that. This is a three year old post, and the OP hasn't posted here in over two years.

I don't know how the OP determined his car came with a white top, but it wasn't from the "A" in the paint code. 63 paint codes are followed by the A on both coupe and convertible bodies.

That I know of, there was never anything on the trim tag, to identify the top cover.

That's what I thought. I can't find anything anywhere stating other wise.
http://stlouisncrs.org/vin_calculator.htm I used this vin decoder. When I put in 912A I get the result A.O. Smith Body. If I take it away and just put 912, It comes back invalid. Now I just have to figure out how this early model 63 corvette has a Smith body, when most records show smith didn't start producing bodies for Corvette until 64.
