Two 8-1/4 Rear Ends - Sure-Grip/True Lock/Posi - Big Bolt Pattern

I got these as part of a package deal for a truckload of parts I bought recently and have no need for them.

I'm not sure of the exact proper terminology for the 8-1/4" in regards to Sure Grip / True Lock / Posi. All I know on both of these is that when you spin the yoke one direction, both the axles rotate the same direction.

Big bolt pattern.

The black one was reported to me to be out of a 72 Dart. Spring perches are about 43" center to center and the distance from axle face to axle face is about 56-3/16".

The rustier one the guy I got them from didn't know what it was out of. It is about 44-1/2" center to center on the perches and axle face to axle face is about 59-1/2". Based on this chart, I suspect it came out of an F-Body. An accurate 8 3/4" rear axle width list

I have NOT opened the cases to check out what is inside as far as gear ratios.

I've never used them, but guys on here have talked about shipping with Fastenal. I do have a local branch here. If you want to get a quote for shipping, estimate 72" x 30" x 30" and 300#. You'd choose the branch in Elizabethtown, KY as the source. https://www.fastenal.com/fast/blue-lane-freight

Local pick-up preferred as I wouldn't have to build a crate that way.

Pricing - I'd have to build a crate for either of them and also drop off at Fastenal.
