TH400 to 4l80e driveshaft question
I know MM is running his Denny's d/s originally set-up for M6/moser 12 bolt in his after just swapping the yoke. I think your d/s will have to be shortened about 3-3.5" if you are running a 4" Th400 tailshaft now.
Best thing to do is get the tranny in the car then measure what it actually is.
