Re: C2 Front Bumper bolts

Ronald, Sorry, I fell asleep reading your lengthy reply BUT, my 65 is a 1 owner, never molested car that has NEVER had ANY bolt removed, including the valve cover bolts. This is a S. Ca. car and all head markings are perfect. My point is, when I discovered that one side of the car had one head designation and the other side had a different one, John Hinckley posted that there were SEVERAL suppliers of bolts for the assembly line and it all depended on what box of bolts were dumped into the tray for assembly. I've only owned & restored Corvettes for 40 years but I find it hard to believe that EVERY car of ANY year used the same fasteners. Please refer to Rich's post above regarding COMMONLY used bolts. To try to match every bolt on your car is ridiculous and wouldn't be typical of factory assembly.

Russ,
What is your build date? 1965?

Build date is March 14,66

Re: C2 Front Bumper bolts

To add to the year/headmark remark....this is "most" common.
63-64 WB with some TR and M thrown in.
65 TR, M, RBW.
66 M, RSC.
67 M, SBC. All years could have a mixing of others but these are a basic guide.

This is for the 1-1/4" GRADE 2 BOLTS

Rich, I pulled some interesting head mark bolts from my 63 bumpers , there not sitting in front of me, But there are RSC with the no. 5 in the middle.

That's correct. Fasteners were ordered and stocked to the line bins by part number, and it didn't matter what supplier they came from or what the headmarks were. The stockman poured the correct part number bolts from the box into the line-side bins, and the guy using them just grabbed what he needed from the bin as he used them. Nobody in the plant paid the slightest attention to bolt headmarks, just as they paid no attention at all to dates.

Ed check them again, they will most likely be SSC or SCC with a 5 in the middle. Not original. I have seen them but they are non factory installed maybe service replacement or hardware store.

Re: C2 Front Bumper bolts

Head marks always bring up good discussion. John spent his career in the plants as I have as well and I agree with how John stated things ran.

But that does not mean that the only surviving cars fail statistics, and we only have cars with mixed head mark bolts - all the ones that that got plugged with bolts right after the guy filled the bins all got wrecked - we have to have a lot more straight cars out there than ones with mixed head marks, there wasn't a guy there stirring up the bin with different head marks so we could debate this 40 years later.

M's on one side TR's on the other make perfect sense with how the factories ran. Having that evidence is wonderful and even better when you do chime in and tell us what they have.

As far as my car with RSC's in all the hidden spots on both sides, it just make sense to replace those that were changed with RSC and to that extent some of us will be looking at pictures or parts in the next day or so to see how those repro's compare.
