Does anyone know the length, pitch, size of the bolts that bolt up the 87 5sp tranny to an 87 T2 block? And the qty of bolts too.
Thanks

The Factory Service Manual in the FAQ has the number of bolts. There is a thread pitch topic in the Archives which contains the sizes.

I've spent as much money on bolts for my seven during the rebuild as I did new oil for it... :/

Can you quantify "course"... "coarse" thread?

Nevermind...

I believe that the course thread bolts are a 1.50 thread pitch (or 1.75) and the fine threads are 1.25 or 1.0. Seriously, a thread gauge is about $5 at the local hardware store and saves a lot of guesswork.
