Cat 3126 swapped, Allison 2000 transmission, np205 divorced transfer case, Chevy seats, air parking brake, train horn, home made front bumper and side steps.
I bought the truck 4 years ago as a pretty much stock truck, It had the 7.3l IDI and an E4OD. A few years back I swapped in a Cat 3126 and an Allison at545 out of a school bus. There is not much aftermarket support for a swap like this so I had to make all mounts and brackets. It took me just under a year to get the truck running and driving, I spent the next year driving the truck and working on the finishing touches. I put about 3000 miles on the truck since the swap and the only thing that needs to be changed is that at545 transmission so I am currently in the process of swapping out the 4 speed for an Allison 2000 which will give us more speed and better fuel economy. The swap is nearly complete and even started up and drove it to the show! Most of the parts I used were either eBay or junkyard parts, I have parts from all different makes and models on my truck, if it fit and I can make it work it was the right part for me!
