CJ7 4bt Cummins swap

Well I figured I'd post some pictures of the project we've been working on the past month. It originally had the 6 cylinder with a 5sp and was replaced with the nv4500 and the original dana 300. Overall, the swap went really well and was amazing the difference the diesel had compared to the original 6 banger. We didn't even have to change driveshafts but with the aftercooler, had to modify the oil pan and powersteering pump reservoir. In the end, it was a lot of work but well worth it. I'll post more(and clearer) pictures of it complete when I can get a sunny day. Sorry for the bad quality in some, they were from a cell phone.

I'm jealous! Considered doing this swap in my CJ but ended up doing a sbc.
