As photoed the engine and transmission are pointed down in the back at 3* (carburetor base level) and the pinion is pointed down 1*. With the tape measure stretched across the span it reads 8*.

Are these angles too high even with such a short drive shaft?

Should I bring up the engine and transmission (carburetor base off level)?

Am I going to need to source a equal distance rear-end?

Thanks for any help!
First thing you need to do is get the pinion up to 3*. The angles need to be the same.

That 8* you have with the pinion down 1* will be more when the angles are the same. (pinion up).

If it stayed at 8* less 3* is 5* angle. They recommend 3* to be optimal but 5* may be OK.

But, with your pinion down 1* and rotating it up to 3*, the angle will end up more than 5*.

The suggestion about lifting the tranny up seems like the best way to go.
