1986 Comanches with the Metric Ton package came with AMC Model 20's with one piece shafts, 4.10 gears, with or without a LSD (1 piece case Trac lok). In 1987 the Metric Ton package switched to D44's in 3.07 or 3.55 gears depending on transmission used behind the 4.0L. I've never held a Comanche M20 in my hands, but I've seen dozens of them under different Comanches online, and the parts books all list them being used for 1986 (only) Comanches. I thought the factory Comanche one piece shafts "could" be a good replacement for the 2 piece wide body AMC 20 shafts, but they're pretty tough to find used, and any leftover NOS shafts have long since disappeared, if there ever were any leftover.

Big cars from 65 on with 232 or 258 six used the AMC 20. Only older big cars with 196 used the AMC 15. I'm not sure about the 66 only 199 big cars (fleet only), but I think they used the AMC 15 for weight savings also.
I don't see why the Jeep 5.5" circle hub couldn't be drilled for a 4.5" circle pattern without welding. You just move over between the holes and drill the second pattern. Any machine shop should be able to do it. |

The problem I see is the wheel centering flange. The flange on the Jeep hub would be much larger. It would have to be machined down (or off completely). Then you have nothing but the lugs to center the wheel and brake drum on the hub. Bob tufcj |

That could be an issue with some aftermarket wheels, but most factory steel wheels are "lug centric" anyway, and a lot of aftermarket wheels are. I don't think it would be a big issue for most.

Wheels probably aren't a problem, but the brake drum is. The lug holes on the drum are generally larger than the lug, and if the drum isn't perfectly centered on the hub, you're going to get a pulsating pedal or spongy brakes. I'm not saying it can't be done, it's just going to take some work to get it right. Bob tufcj |
