Hi mopar friends!
I have a 1973 Plymouth Satellite Sebring Plus. I'm having a nearby shop remove the leaking 727 slushbox and replace it with a TREMEC 5-speed manual trans (and new driveshaft).
I know I will want to change the gearing ... probably to 3.22. Is it possible to upgrade the diff to posi at the same time? Who makes such a kit?
I also plan to keep the original 318LA block, and get up to 400HP at the crank with top-end upgrades only (carb, intake, heads). Will the 8.75" diff I have in the car take that kind of power? If not, what kits are available to prevent axle twist under load? I see some $100 weld-on kits as well as some diff covers and axle braces from LMR racing. Anyone tried either?
