The restoration is advancing quickly! But, as in all restorations you lose bolts, break them, or they are just too rusted to be used again.
I'm looking for the thread sizes for the following items:
: crank pulley to balancer bolts, ( coarse thread i think?) ( 3x) :
- Door hinge bolts ( 16X) :
- brake caliper to wheel hub front and back :
- fuel tank float to tank screws :
- shock absorber upper bolt ( rear shocks)
Who can help me? afaik these are the last bolts I'll need to buy before the car is back on the road. But being imperial bolts and not having the original ones it's a bit hard to figure out wich ones I need exactly.
Hi D,
I'll start:
The rear shock absorber upper mounting bolt is an odd one. The bolt has to have a very short threaded length in order to prevent the threads from abrading the rubber bushing in the shock.
The thin nut is required to get the nut in place in the space between the shock mount on the frame and the underbody.
It's 7/16x20 grade 5 bolt.
Regards,
Alan

It's madness! I had to order 3/4-16 UNF half, left hand thread nuts in the UK because no one in The Netherlands had those.
I did manage to buy an imperial "tappenset" (UNF/UNC) for about €40,- which has a "draadmeter" for UNF/UNC. So I can now both create imperial threading (needed it for my hydroboost mod) and measure bolts to see what threading they are
Hi Dusky,
I'm in a similar boat.
Just received my first ('69 coupe) Vette. I'm well-stocked for metric bolts and nuts of all sizes, but don't have any SAE/Engelse hardware.
Let ask, would you have found it useful to have purchased a "set" of SAE bolts to have on hand? This sort of thing for UNF and for UNC, for instance:

That's 41 Euro and another 41 Euro for the UNF set.
Worth it?
Thanks,
Hi,
I bought assortments here : https://www.zollschraubenshop.de/sortimente/
But ended up buying a lot of "one off" stuff there as well, especially for the grade 8 fastners.
I'm already restoring my next corvette now, if you'd need 1 bolt or something feel free to pm me. I'm guessing you're Dutch by the .NL website, im Belgian but bettered my life by picking a Dutch girlfriend..

Well, I'm not Dutch, but I do live in/(just outside of) Amsterdam. (I'm American)
I "bettered my life by picking a " Singaporean wife... ;-)
Since you're being so helpful, let me ask if you have any recommendation as to whether I should buy (some sort of) assortments or just wait and get the 1-offs as needed?
To be fair, my car is in pretty good shape - I'm not performing a restoration - but there are still plenty of 53 year old bolts to take off as I wade through the issues with this car.
Thanks, again,
Steve
