trans mount bolt threads

Drive shaft hits the e-brake thing in the tunnel. So it the trans mount needs to be lowered. I tried washers, but it still hits. Next I'm trying replacing the weird cylinder with two studs on each side with a longer bolt, washers, and nuts.

What is the thread size?

thread size? d-shaft hits e-brake guide in tunnel, so need to lower the trans mount bracket.

Does the replacement bolt have to be a super strong alloy that can be found at h-depot or lowes ?

drive shaft hits the bracket that the e-brake cable is guided through. there are wear marks on the drive shaft, and the e brake guide is shiny from wear

the car had a bad wreck and was rebuilt way before I bought it.

I have been trying to find new ones as well, either SS or Grade 8, but no one sells fine thread metric! Sucks!
