I have the 5sp 3650 in ANGIE shifts great with the short throw Hurst and Royal Purple Fluid. The new 6 sp ,they have problems too, and may be a longer trans, you may have to shorten the driveshaft , ( 6sp just more to do ! ) Change to the Royal Purple !!!
What was the gap on the stock hood 1/8th inch on both sides ? What are the gaps now with the new hood ? Can you move the hinges to get the same gap on both sides ?
You had to move the fender to get the R hood to fit ? The R hood must be a little wider or narrower than the stock hood ? Did you make the same mistake as the bumper that wouldn't fit ?
