I doubt that 400 np 435's are all that rare I parted oiut a club cab 73 d200 that equipped that way. Most of the drive train is destined for my 76 d 200. I first found the truck when I needed a dana. It donated the center sectionto my 76...I then robbed it of the black adventured interior and the power brake/steering for my 72.

The truck was at a friends salvage yard the ownwer kept the 400 and the 435...I tracked him down and bought that last summer it was low mile rebuild and came complete with the rad/carb exhaust manifolds and even the wiring harness and all the pulleys and ps pump....a complete big block swap kit!
