I got a 85 ford housing just like that a couple months ago. Not sure if I'm going to cut the tubes off and swap them to passenger drop for my current buggy, or leave it as is and build it with GM outers for my next rig.
That is the route I went, Chevy Outers on my project. Bolts right on and the claim to fame is that they are somewhat less prone to breakage
