Can someone tell we the dimensions of the 3 studs that connect the exhaust manifold to the exhaust pipe? (1972 Z)

Searched but ran out of steam...

Thanks!

Thanks but it doesn't tell me the length

Take the p/n, search for it and dig around. You will find specs.

Actually the part number tells you the length. 08213-82810 The length is 28mm.

These cars require a tremendous amount of time and research to find the available suppliers. That’s the biggest battle.

I found I like these SS studs from Amazon. Ford engine spec.

I love the hex internal drive on the end, makes inserting them easy. Cut to length as you need to. I also like the price and quality.

I do have a ton of their flange nuts left over, i rarely use those. Belmetric has m8 nuts with 12mm heads that are yellow zinc plated

I can't imagine thats the total length though. I saw somewhere its an M8x1.25 x 45mm which makes sense, just wanted to pick the brain trust here.

Could be that they changed over the years.
