Slant 6 to 318 swap, 72 Duster, Using 75 D100

As for as i know they are sure grips but im not sure of the size yet the only thing he had told me was that they were possies but i haven't gone to look at everything yet, hopefully he just dosnt know his mopar lango and they are sure grips. they should be full axles and diffs he said.
both have titles and the 75 is back registeresd to july and the 77 is non op current.

The duster is running and driving daily but has blown head gasket on th /6 witch a new kit was already purchased and it was dirt cheap.
