Hey,

Anyone heard from Groovy Jay? He did something similar, except hand fabricated a new bumper...

I personally like the idea, once the frame rails are carrying the load, the stock bumper has 3 inches or so of energy absorbers before the bumper hits the frame.

I thought we had a fuel cell, complete with rubber bladder. Anyways, I fabricated another bracket to eliminate the flexing in the wind licence plate holder. It would have been much easier to do this with the bumper off, but that is too much a pita. The plate area is very solid now. In fact, the whole rear bumper, with my aluminum cross brace with the tailights and license plate attached is very sturdy. Maybe not sturdy enough for pushing, but I bet it's as sturdy as anything the pre 73 sharks have. I'm done, except cleaning the adhesive, polishing, waxing, and remounting the spoiler. So what did you do over the holidays? I lost 55lbs.

Yep, I got the idea from Groovyjay and his C3R. That is a wicked car.

you got a gas tank. fuel cell..racing cell...can take more abuse.

need to do something right? cause 55lbs isnt worth the risk if rear ended. the aluminum is going to cut it.

Safety is a relative term. After riding a Harley for twenty years I feel quite safe in my Vette - with or without bumpers I still have a lot more protection than anybody does on a scooter. I'm surprised you safety freeks can feel safe driving these old cars at all. No air bags, antilock brakes, traction control, etc. You must be peeing in your pants everytime you go out for a drive.

wow, a real live Harley...all loud and stuff. neat.

I guess my old ZR-6 is slow....

Danger is danger...but when you can negate some it seems silly for 55lbs... the risk to reward seems silly. but to each thier own.

The shaved bumperetts look cool on the other hand...the 2.5mph collision i will risk... just not the exploding gas tank.

BJ, you're not alone in your battle

You should consider to swap the stock windshield with a lexan one, i've bought a 'speedglass' windshield 2 years ago, it's light, more transparent then the stock one and is still nice and un-scratched, of course you need to take some extra cares...

I've been a motorcicle boy all my life as well, i've risked far much more in my fxr (and ducati ss...and aprilia 250 two strokes ) then all the risks i've taken on my lightened vette the last 5 years...and then, yes, stock C3's are a kind of cruising open graveyard for safety anyway, with or without rear (and front) defenses...

That is a beautiful car! What color is that? But isn't that a stock '80 rear bumper glassed in? So, it would be just as long as my 79 bumper but with a spoiler built in. I was wondering how our bubble back cars would look like with the much shorter 68-72 rear end, minus the chrome, just like Kid Vette's.

I don't think it would look quite right. The glass nose cars have longer fronts to accompany the longer rear. If you were to shorten the rear, you should shorten the front too. Not that I can see any way to do that... Other than swapping a chrome bumper body on there.

I dunno. The 73 had the rubber nose, and chrome bumper rear.

Thanks Bee Jay!
The color is Code 28 Dark Blue Metalic (the original color) and the interior is Oyster. It normally doesn't look that blue. The sky was crystal clear and brilliant blue that day, and made the car look more blue. It looks more gray on a cloudy day.

No, I don't have stock polyurethane bumpers. The front is fiberglass and the back is FlexGlass (which I don't recommend if you're going for the seamless look).

I'm not 100% sure, but I think the '80-'82 bumpers fit on your '79. I think some CFers have done the swap.
