Re: 87 Crew Cab 454/TH400 to Cummins/NV4500
Okay, once the body lift was in it was time to continue moving forward with fitment and mounts. I mimicked the drive line angle of the 454/th400 very closely. I was also able to find a mounting location that eliminate the need for drive shaft modifications. The NV4500 output yoke was moved rearward slightly compared to the TH400, but I was able to compensate by moving the carrier bearing rearward slightly ( the hose are slightly slotted). The original cross member was also re-used by cutting clearance in it for the larger NV4500 tail housing. I was able to bolt it through the original hole by rotating the rubber transmission mount (that came with the NV4500) 180* The stud is offset front to rear slightly and this compensated for the difference almost perfectly. Unfortunately I did not get photos of these aspect but when I get a chance I can put it up on my lift and get pictures of this.
