I did a whole rear seat delete, got a roll bar, and racings seats, did away with the stock seat belts and am putting in some 5 point harnesses.

I planned on using the stock seat belt mounting holes, however the stock bolts are too short to go through the harness brackets and get securely into their spots. So with no way to bolt in the harness, I have no harness.

My question to everyone here is, does anyone know the thread size of those bolts or where I could buy replacement ones, perhaps ones that are longer?

 

Go to safe racer.com for 50mm eye bolts and angled brackets ,etc.

no to mention using a 5pt is illegal on the street. the only DOT approved 5pt is a scroth camlock set. everything else is illegal. if you do it right, you can keep both the stock and 5pt. ill also add that i hope you have a seat WITH an actual sub belt slot, and youre not planning to just run the sub belt over the front of the seat and attach underneath, which is stupid, wrong and dangerous.

saferacer has eyebolts, which i use, but they dont have any kind of angle bracket needed to make everything fit in the stock locations. i got a heavy 2 hole angle bracket from work thats designed to hold up heavy equipment in ceilings. try lowes or any hardware store, and get a heavy duty angle bracket. i use a right angle bend for the door side, and a 45 bend for the console side.

 

What is the thread size? I am looking at like a hardware store to see if they have something similar... Anybody know?
