My son and I did this conversion on his 71 Challenger. You will also need the shifting tabs on the side of the tranny. A small but important part is the small bracket with the studs that acts as a stiffener through the cowling next to the master cylinder for the clutch pedals. I believe on 1970 E-bodies, the master cylinder had a bigger plate to act as the cowling stffener to be correct. If you put in the clutch start switch, you'll need to wire it in. Also needed is the clutch fork return spring.
