Spare Tire Carrier questions
After getting 775X15 redlines (BFG Silvertowns) on my '67, and getting dinged for cracked glass on the spare tire carrier tray, I decided to replace most of the assembly. I ordered the longer, redline front bolts and locking bolt from LIC, and put on a new barrel nut and pin. After getting it all back together, when I put the 775X15 bias redline BFG tire in, I had a devil of a time getting it closed and locked down. I had to partially deflate the spare to just barely force the tray slot onto the locking bolt cranked down all the way to the pin stop. I am thinking it just shouldn't be this tight with no play and adjustment on the locking bolt. Are these bolts really the longest ones, or maybe I need longer ones?? And ideas welcome, thanks.

Michael -- if you got LIC's #11-4C's [hinge bolts, GM # 3872958, length from bottom flat to top flange [the part that contacts the X-member] of 9.40"; and lock bolt LIC 11-13C, length 5.0" from the flat of the groove just next to the hex, to the flat flange that would contact the barrel nut if no tire were in the carrier; GM # 3872959. Dimensions and part #'s from Noland's Vol 2 pg 300/301.
Other than that, there's no other available, unless you custom fabricate. -
Re: Spare Tire Carrier questions
Thanks, yes those are my part numbers, and that is what I was afraid of. Guess I will have to put some washers under the two mounting bolts that hold brace the lock bolt and barrel nut fits into to get the extra 1/2" or so I need for play. Not sure what is out of whack here, but with a 43 year old car,anything is possible, thanks.Big Tanks In the High Mountains of New MexicoComment

Re: Spare Tire Carrier questions
Michael -- another thought; this is what I do to get my goldlines on '66 KO's to fit nicely [without buying the longer bolts
] . Slip on a few (3 or 4) washers at the threaded end of the forward hinge bolts, then screw on. Check that threads are fully engaging the nut welded on the inside of the X-member (stick a finger through the adjacent hole; there's way more thread on the bolt than is necessary -- anything protruding above the nut is wasted thread). This will buy you another 1/4" or so, which translates into an even greater lock bolt flexibility.
Good luckComment

Re: Spare Tire Carrier questions
Right, great idea, thanks! You do wonder how much play there was originally. My brother ran a Goodyear tire store in the '60s and '70s and he remembers how much a pain it was when a Vettes came in. The mechanics hated it, crawling under the dirty car on a dirty floor to get that spare. Yet another bad engineering design by the GM engineers, kinda like the battery location on the SB C2s.Michael -- another thought; this is what I do to get my goldlines on '66 KO's to fit nicely [without buying the longer bolts] .

Re: Spare Tire Carrier questions
I'm running into the same problem with my redline spare. I have the longer bolts but the carrier is still too tight on the rear where the tire lock attaches. If you put washers/spacers under the two lock bracket bolts won't you lose points in judging also?Comment

Re: Spare Tire Carrier questions
Try this for judging only. Just don't screw the two long bolts in all the way. Leave about 3/8 or so before bottoming out. Any fair judge would only deduct a point.
The only violation is assembly. Configuration, finish and all the rest will be correct. Damage to the fiberglass tub is a condition issue and another deduction based on severity.Comment

Re: Spare Tire Carrier questions
Another possibility is the new tires are wider than the originals. I am not a midyear guy, so be nice. But I have seen that problem with newer Vettes...Last edited by Richard L.; October 14, 2010, 07:46 PM.Comment

Re: Spare Tire Carrier questions
Mike-
the release for the tray is right under the license plate, as you know. No one has to crawl under the car, or hardly even reach under the car to get the spare out. If you actually use the handle of the lug wrench to lower the tray, (I haven't used it yet for this purpose), you don't have to crawl anywhere, though you do have to get down on your knees. And, I can't think of one other place to put the spare, (or the battery for that matter) unless it would be on the shelf space behind the seats, and that wouldn't work very well.Comment
