4R70W mount to transmission bolt size?

[JoshT]

Trying to finish up the transmission portion of my V8 swap into an '86 Ranger, which is mostly the mounting. I think I'm going to use the stock explorer mount and adapt the Ranger cross member to work. I removed the mount for clearance when sliding the engine and trans into the bay, now I can't find the mount bolts.

So anyone happen to know the proper bolt size for the 4R70W trans mount to trans bolts?

Thanks!
