I am thinking of swaping out trans rear axle. does anyone have info needed to do this correctly? which rear axle fits? who's rear suspension link system works? I plan on keepeing my lowered rear springs and would like to say with the 5x5" bolt pattern.
I dont have dimensions but a couple I know of were done here in NZ using a Ford Lincoln 9 inch rear end, and maintaining the 5x5inch stud pattern. The 56 was a Roadmaster and used the original torque tube trailing arms (modified mounts at front) and a 3rd link from the top of the rear axle housing to a modified front crossmember. The 57 used a Lincoln rear end also but used a triangulated 4 bar mounting system. I plan on converting my 56 Special also to a Ford rear end but dont yet know of any easy conversions without fabrication and engineering.

Someone from this shop may be able to give some detail on the rear end width etc, also http://www.barrett-jackson.com/application/search/w_search.aspx Have a look at this site Lot #1577. A 55 Buick special also nicely converted by www.goprorides.com Hope these help Ross
