Spare Tire Carrier Bolt

[Irby G.]

Hola everyone,
Could someone tell me...is this bolt for '63 only? All cars for that year? Is it the only bolt used during that year?
Thanks,
Irby

Re: Spare Tire Carrier Bolt

If you look in Noland Adams book "TCCR&TG VOL-2", on page 108, they show this being the first of three different styles of these bolts, used in the 1963 model year.

Hi Lynn.
Yep that's the monster. Thanks.
p/n 3820414. It doesn't say what the vin cutoff was, just that it was early '63. I have a vin in the 4900's born in mid Dec '62. All I could find was one of these with the car. Does anyone believe that in Dec '62 this was the carrier bolt?
Aloha,
Irby

63 only, very early. I do not know the VIN cutoff.

Re: Spare Tire Carrier Bolt

Does anyone know where I can pick up one more of these? (I think I know the answer to this ? but had to ask). I'm also wondering how difficult it would be to have someone fab one for me?

First of all, it might be that the 2 different style you have on the car are original to it, especially if the other one is a GM #3833383. I think it's possible that both styles might have been used during a "transition" period. Of course, who wants a "mismatched" pair even if it's original to the car and would it be acceptable from a judge's point-of-view?

Of the 3 style bolts used for 1963, only the 3833383 and 3841463 are, as far as I know, reproduced. You might check with Long Island Corvette, though. If anyone has a reproduction of the early style, it will likely be them.

As far as having one made, I'd say forget it. It would be difficult to reproduce this part in a lathe and no one is going to create a forging die to make-up just one (or, even, a small lot of them).

A set sold on eBay yesterday for about $175.00. It was a nice set. The price says how rare they are.

Joe & Harry,
The pictures of the '63 GM #3833383 looks like the head is completely round. It doesn't appear to have the two sides 'sliced' off like the pictures at LI corvettes are. I'm looking at the picture on page 109 in Nolan's book.

Re: Spare Tire Carrier Bolt

Best I can recall the picture you posted is the first design. The round head or bottom is the second design and the one that looks as if the two side were sliced off is the third design.

I have an April 63 car and I have the second design.

I think there may have been 2 versions of the 2nd design GM #3833383, although only one of those was used for 1963. I think the 1st version of the 3833383 had a completely round head, but later versions had the flattened sides. Most likely, this occurred due to a change at some point in the specification of the 3833383. The 3833383 was actually discontinued from SERVICE in May, 1965 and was replaced by the 3841463. Then, it "came back". I think when the latter occurred, the change in the head design also occurred.

In any event, for 1963 I THINK the 3 different bolts can be best identified as follows:

1st design------hex head, "free" hex head nut at threads;

2nd design----round head with NO hex, welded-on nut at threads;

3rd design-----"flattened side" head, integral "pedestal" replaces welded-on nut above threads.

Later (ABOUT 1966 or 67), I think the 2nd design (GM #3833383) "came back" in modified form with "flattened side" head.

Re: Spare Tire Carrier Bolt

we did a 63 # 600 or so a few years back and it had a pair of those on it, they used jamb nuts, but were not welded

Yes, I believe I "mis-spoke" with respect to the configuration of the 1st design bolt. I think the first design bolt did use a "free" nut as you describe. I'll correct my previous post.

If you are going to be at the Kissimmee Meet next week I believe you should be able to find a couple of sets laying on a table.

Hi Joe,
I wish I could make it. I haven't been able to make any corvette function yet (Carlisle and such). Maybe one day. If anyone finds one, I'd love it if you would pass me their name or email addy.
Aloha,

Re: Spare Tire Carrier Bolt

JR, I'm not sure I would go to Florida if I lived in Hawaii!

Irby, If I spot one in Florida I'll pick it up for you, what is your price limit. Please respond with an email.

Thanks
