Really ? . . . Our junk yards have no diesel's period . . . they auction off them truck's as soon as they come in . . .
I would rather have an operational truck and swap Cab's n bed's onto it, Buy a 89-93 ram dually 4x4 diesel manual trans drive it toss on a set of 19.5's drive it a while get the motor built to spec, by that time it's paid off, then track down a Jeep Cab and try and buy a nice Flat bed, swap the body on to the dually chassie.
I really don't want to buy and engine then a transmission then axles then try and find a whole jeep. to many step's it'll never get built lay around a few years and hauled off for scrap, Which would be a big waste IMO.
Keeping it simple makes it get done I know myself all to well
Plus bank won't lend you money to build a truck, from a pile of parts But they will let you buy an old 1 ton Ram as a "toy Hauler", then build the rest of it I'm doing they call Creative Financing
Wrecked 2 dually chassies 1 RAM3500 diesel and 1 GM3500HD and 2 J truck bodies, It can be drawn but it can NOT be built.
The RAM chassie I couldn't get the front axle to center in the wheel well. So I removed the 12V-Cummins and got the body setting right couple of test fits with the 19.5s all was good. Then came re fitting the power train everything seemed to interfere with something else. Lost my cool one day the J-truck body RAM chassie n cummins diesel all went to the crusher and was destroyed !
So I spent 3wks thinking then I remembered about the 92'-98' GM-3500HDs those came with 19.5s and heavy GVWs.
The GM chassie was easy to find, bought a second rust free complete J-truck front half body n chassie fit together queit well excpet for the huge wheel well gap from top of tire to bottom of wheel well, chalked it up to missing engine test sat a BBC under hood didn't squat enough. So I bought a 24V cummins diesel got that sat. Into place but still looked ugly but I got driving around anyway.
After trying to run a size bigger tire then another size bigger tire still not looking right. This is when I realized the GM floor pan and Jeep oor sit differently. The Jeep body tho mounted at same hight visually appeared 6" higher because the jeep body sat mid frame rail and the GM sat below. So after trying to lower the body to no avail I crushed it ! ! !
So 2 perfectly good dually 1tons wrecked, 2 rust free J-trucks destroyed, and 2 Cummins diesels wasted I gave up thousands $ in the hole and hundreds of hrs wasted.
Now I didn't try using a Ford Chassie yet ! ? !
But I went another route bought an 82' J/10 Honcho stepside shortbed I'm going to swap J/20 Axles n springs under it drop an AMC-390 under the hood mated to a T-18 with 4.27gears and Run polished SRW 19.5 rims, add a Goose neck ball and heavy duty receiver hitch.
I felt this was a better route instead possibly wasting another 1ton chassie and J-truck body !
