I'm looking at a 72 Maverick 6 cyl automatic that has a good body and a 74 Grabber v8 automatic that is not in that good of shape. My plan is to use the 74 as a parts car and build the 72. Wanting to go with a 302 auto in the 72 so I can get the parts from the 74. Will also get the axles, front and rear. What else is interchangeable between the two cars? TIA, Chris
