M20 is the RPO.
Not the trans type.
I think you might need to pull it apart.

Damn dangit dagnabbit.

Any tips or hints? Support engine with floor jack.
Grind, chisel, drill out rivets for crossmember.
Drop driveshaft.
Use tranny jack on tranny to lower.

Is that about it? Best way to deal with rivets?
Heard using a cut off wheel/angle air grinder to
X them and then is air chisel to chisel for 4 pie shaped pieces was not bad.
