I just purchased a project recently. 85 Monte NON- SS came from the factory with 305 but previous owner ditched the orig engine and trans. Currently has a 327 sbc and a 2004r in the car. I had to finish the install of the trans. the driveshaft, shift linkage work that came with the car but the crossmember doesn't look correct. The rear trans has 2 mounting holes and the crossmember has 1 hole? I have read you can slide some cross members back to the rear holes in the frame but not sure this will work with mine. Any suggestions? I have a feeling I have a crossmember for a th350 or a th200 trans.?
