Anyone know the size of the bolts that mounts that rear mount brace to the rear mount? It connects to the transmission. There is like 3 of them.

I thought it was M14 x 1.5pitch....

 

I was right, those two 19mm head bolts on the rear mount brace are in fact 14 x 1.5 pitch if anyone needs to know....

for some reason, I the die wouldn't thread onto the bolt, but the tap thread into the tranny just fine.

 

Good to know.

Could've been really gritty - try spraying some WD40 on to while threading.

 

Actually, in my case, it was a brand new transmission. After I cleaned up the first couple threads, I sprayed some brake cleaner in there to clean it out. Next time I'll make sure I put this bolt in first.
