I own a 70 ss with a 350sb/3spd Trn./373 rear. I'm very pleased with this combination, however Im not over excited about rebuilding the car. My original intention was to get a 69 but couldnt pass the deal I got for this one. My question is can I swap the Engin, Trany and Rear from this 70ss to a 69? If so would it be worth it?
