I be darned it got where i wanted it.
Besides the 8.8 Ford there are a couple other Ford pieces that will fit, a couple of them are close to drop ins as far as the spring perches go. Maverick/Comet, 57-59 9" out of the Ranchero or wagon (right width also). 65-66 Mustang, 74-78 Mustang II (rotten 4 bolt wheels). I am going with a 69 Mustang 9", little bit wider than an A Body by 1 1/2" (about the same as the narrow B Body 8 3/4), spring perches can be filled and redrilled to the propper spacing. A Body 8 3/4 are pretty rare in this neighborhood, and when you find them, a month's salary to procure them. Good hunting!
