Matt’s rear differential has an lunchbox locker that’s been on the way out for some time now… so he enlisted me and my team to set him up with a fresh third member loaded with an OEM Non-US Limited Slip from my stash. Along with new ring/pinion, bearings, pinion flange, and solid pinion spacer...
I am surprised you didn’t de-pin and replace the TPS receptacle housing, it’s always just the plastic housing that is cracked
The locking clip on the IAC usually breaks too so watch out for that. Usually we are replacing both housings
