Collecting parts for av8 build. I currently have a few options... Motor is a 38,transmission is a 38 also. For rear ends I have a couple options that I have narrowed it down to. I have the stock Model a rear with torque tube and everything else. The 48 has no torque tube. The motor is stock 85hp. Model a rear could be fitted with the 48 brakes... If I went this route, drive shaft/torque tube can be left stock length? With the 48 brakes are ready to go, rear end is stronger, but it is 4 inches wider. Thoughts?
