tranny bolts

[bigrod118]

would anyone out there happen to know what bolts are needed to put the tranny onto the motor. I know there 12mm, but I cant seem to get the pitch right, but right now im soaking the holes in everything from carb cleaner to liquid wrench to clecn them out, thinking its just dirt in them. I need to get this motor onto my engine stand and I need the bolts to do so. so if anyone happens to know what correst pitch, it would be a great help.
