I've only seen one report that someone hammered a right rear floor board/tunnel area over a touch.Pretty sure it was a small car. Doesn't seem to be any issue at all with large bodys. Since the rear floors on that Marlin are laid out for the torsional support bars of the torque tube there should be zero issues and if there are they will be minimal. The side offset does not affect driveshaft harmonics at all as long as you keep the ujoints in phase and the trans and pinion shafts are straight and equal for to aft.

I'm going to put this here and hope it gets noticed.

I'm trying to figure out what rear axle to use in my Ambassador?
I'm using truck arms, panhard, and possibly bags for springs.

This beast is going to be a very far off the beaten path TOW RIG for our boat!
Plan on a class 3 or 5 hitch behind the license plate.
327, 4bbl Turbo 400 to what?
8.8"
9"
Grand Cherokee AMC 20, I have a twingrip unit and those have one piece rear axles. I can get it redrilled to 5 X 4 1/2 and the other demensions altered to fit discs.

Ford used the 8.8" in exploders and 1/2 ton trucks, so it is a good choice. Maybe real good due to I'm using one in the American.

The AMC 20 has plenty of beef since it looses the two piece axles. there was one fro sale local with 3:31 gear set too.

I've tried to find the stock width WMS-WMS on the stock rear and found nothing but track width or backingplate width. I don't get why those are even used other than a comparison.

For the big cars the Ford Explorer rear axle may fit, but the 93+ Ranger is 1.5" narrower.

Since the old 60s wheels are pretty much all centered, track (which is center of tire to center of tire) is pretty darn close to hub to hub measurements. The only thing to remember is that's not the case on the later truck/SUV axles! They all use a deep offset wheel, so the axle is 2-4" wider than track. You can get the Ranger/Explorer axle measurements from www.therangerstation.com (might need to leave "the" out...).
