Will the driveshaft work and flexplate? 2.how will i make lockup work? 3. What else do i need to kno to make this swap work?
The TH350/350C uses a Detent cable for Passing gear, it's adjustment not critical like the TH2004R's TV/ThrottleValve cable is.
#1 Driveshaft & Flexplate should work fine.
#2 If you have a TH350C Trans it will have a Lockup TC/TorqueConverter, the standard TH350 doesn't have a Lockup TC.
#3 May need to adjust the Shifter linkage.
