1970 NYer Disc Brake Caliper Bracket BOLTS

[330dTA]

I had to move both my car, and all the parts from one garage to another several times. It's a long story.
Anyway, in the process I lost the bolts attaching the caliper bracket to the spindle (as well as the calipers).

Does anyone happen to know the size of those bolts?

Even better, if someone has a few of those bolts laying around. I'd like to buy a set. Will pay decent price for decent items.

Thank you!

I have this from my ‘73 NYB. I’m thinking they are the same but not entirely sure. The treads are 1/2-20, 3/4 head, 2 1/2 inch long shaft. Hope that helps.

Thank you! So, a half-inch bolt with a 20N thread. (I read that scale to show the length to be 2 and 1/4”, rather than 2 and a half. Correct?)

Yes, sorry, I just double checked, the bolt length is 2 1/4 inches.

Thank you. So it is altogether a two-and-a-1/4" long bolt, 1/2" thick with 20N threads, and needs a 3/4 " socket.
There's a 1/8" thick washer, and the hex head is 3/4" thick. So the threaded part is one and 3/4 inces long.
I will source the bolts based on that. If it turns out to be a bit too long, I can always grind the extra off.

Thank You, @Samplingman !

I'v got a box full of that type of bolt, but i don't remember, know, what cars that i took them off of.
Thread length on them is 2 1/4" inch.
