Pinion Angle

[SpeedThrills]

I'm thinking of using the trans pan (727) as a reference while setting the pinion angle.

Anyone know if the pan is parallel to the output shaft/crankshaft?

Doesn't appear to be.

I'll have to quick pull the tail plug and install the yoke to get a surface, I guess. It has fluid in it.

You can pull the starter no mess involved.

Just use the flat on the rear of the extension housing. Kim

I like to get the tranny angle to zero. 67-72 have a 1/16 to 1/8 shim between the tranny and the mount from the factory Kim

I haven’t been under there for a while to see that flat. I would have been asking if it is parallel! Thanks
