I have a 65/66 Mustang 8 inch ( 57 1/4 ) under my Gremlin....has held up fine behind a 360/727 combo with up to 290HP to the rear wheels.....might not be enough behind a 4spd or trans brake.....I am planning to put a 401 in front of it so will see if it is up to that task. I am using a 8" wheel with 3 3/4 inch back space and a 10 inch wide tire... fits nicely under the rear....The center section is about one inch shorter than an AMC20..... anyway Ford 8 & 9 inch info.... http://www.enjenjo.com/9inch.html http://www.woodyg.com/fairlane/finfo/fordrears.html http://www.dfwmotorsport.com/Fairlane/9inchrearends.htm Jim ------------------------ Yahoo!
