Okay I got a 413 I'm installing in my '63 D100, wanting a 4 speed 833, don't need to retain factory crossmember and bell housing with mounts as leaf springs are getting replaced with IFS front suspension. So with that said, what bell housing can/should I use (found a 2892262), 10 1/2" or 11" clutch and I'm guessing a 833 with a input that fits said bell, my current 3 speed has shifter fitted on front of tail shaft (sits in front of bench seat) so shifter mounting area on 833....might be too far back with tail shaft shifter mount. Anything else to look for. Haven't looked at the steel crankshaft for bearing fitment yet. Oh should I run a McLeod hydraulic t/o bearing or has anyone ever done a manual linkage with a truck? Thanks you guys are the best.
