I got to change something. I recently changed to a 468 bb and rebuilt the turbo 400 but the gear in the rear is too low-4.10 or a 4.56. Has anyone changed out ring and pinion for this (10 bolts on the cover) and drop-out front rearend. The truck is a 69 c-20. Are there any suggestions for swapping to a later rearend and what would that be-I have a coil spring set-up. Thanks
