Saab engine to a RWD setup?
why would you?
them engines build up sludge in crankcase bad ,but that because the exhaust runs close to oil pan ,but i guess you can reroute it and prevent that from occurring.
will this be a automatic or standard trans you want to apply?
input on trans will be a problem for you .
a auto would be easier to do .
a 1/4 inch plate of steal for making a trans plate adapter ,
then a small enough trans like a 4 cylinder ford ranger to have small enough bell housing maybe .
you got to use the hole kitt and caboodle .
so do you want kitt with your caboodle as the commercial says for com-cast?
