ok so i might need a new rear for my mav...what width should i get it...and where are the measurements taken from...i might be able to get an 8.8 aswell so my mistake may end up as an upgrade...my mistake is wet roads plus a curb = more front end work and a possibly bent rear...hopefully a bent rim
You're not likely to find one of those anyway. Only Lincoln Versailles models had them, and they were "one-leggers" with 2.50:1 gears...
And the Versailles rear was also available in the Monarch as well and also had Traction Loc. and drum options. One of these I had came from under a Monarch, and had 2.50's with Trac-loc. Had another from a Versailles (351W car) that was 2.50 with an open diff. Seen one under an 80 Granada in Houston a few months back that had drums. The 57-59 Ford 9" rear is a bolt in and has identical measurements as the 8" Mav rear. These often had 3.70 gears and WAR case center housings.
Wheel flange-to-wheel flange distance on '77-'80 Versailles rear end is 58". These 9-inch rears with factory disc brakes were available (optionally) on the '75-'80 Granadas and Mercury Monarchs. They were standard equipment in the '77-'80 Lincoln Versailles. MOST of these rear ends had open (single track) differentials, but not all of them. SOME had 2-pinion (spider) gear Traction-Lok differentials, and some had 4-pinion Traction-Lock differentials. There were only (4) rear end ratios available for these 9-inch rears: 2.47, 2.50, 2.75 and 3.00:1. 1979 Lincoln Versailles rear in my '68 Mustang: http://img502.imageshack.us/img502/8302/versaillesrearendeo3.jpg There were also some 9-inch, drum brake-equipped rear ends installed in the '75-'80 Granadas/Monarchs. This is a photo of the 9-inch (formerly) drum brake rear end I bought a few years ago from an '80 Monarch that was powered by a 250 cubic inch inline six. I converted it over from drums to SN95 Cobra discs (this is the rear end that will be replacing the Versailles under my '68): http://www.ultrastang.com/images/2006/cobrabrakehosemount0243cf_2.jpg http://www.ultrastang.com
