There are some 8 3/4 truck housings out there but they seem to be hard to find in my experience anyway. 1968 Plymouth GTX 1974 Dodge P/U Long Bed Stepside 318 2019 Ram 2500 6.4, auto, 4WD

Steve, PM me...I have a truck housing less the backing plates, 2 sets of the proper 5 on 4 1/2" axles and a 742 chunk with sure-grip. Also a set of OEM steel slots for a Ramcharger SE or LRE proper bolt pattern. All in decent shape that I might sell. I am up in Maine so there is a bit of travel involved.Let me know if you are interested, Mark Last edited by Mr onetwo; 05/06/19 08:55 AM.
