5-lug to 8-lug conversion on Chrysler motorhomes

[Fred Timms]

Anybody ever do this swap? Have a guy not too far away with the remains of a '78 Georgie Boy Country Aire motorhome (25-footer). Has the Dana 70 rear and disc brakes, both 8-lug. Was wondering if this is good, swappable pieces to take my Travco 320 from 5-lug to 8-lug. My concern is that the brakes are not the same size, being a coach that is 7 feet shorter than mine...guy isn't certain if it's an M-400, 450 or a 500.

Looking for thoughts/answers- definitely not interested in smaller brakes/wheel combos, trying to work it for the 8-lug so I can get some Alcoa or Accu-ride rims for my Travco as an upgrade, LOL!

I've converted pre-'73 Chrysler A-bodies from small bolt pattern (5 on 4" pattern) to large bolt (which is 5 on 4.5"). Since the spindle size is uniform across the board in '73, you get larger wheel bearings and can go from 10 3/4" discs to the 11 3/4"-12" (off the B- and R-body offerings) , no sweat.

Definitely never downsize my brakes. But with this M-500 chassis, I know very little so I am looking for experienced voices who would know where to look/what will work.
