Ahhh, just post stuff here on the thread, Len....Nobody around here is too fussy if things are "computer correct" or not!!!!! Seeing as how you have ready access to donor cars, you might also want to look at the Crown Vic's and Grand Marquis that have the removable front crossmember. I don't recall what years they are, but they are a bolt on unit and could be adapted to the Ranchero frame with some crossmember mods to the '57 frame!!! You'll end up with good steering and brakes and a good ride to boot!!!! Just one more option to ponder! I've seen some of these units adapted to F-100's, and one that was done on a '58 Ford 2 door hardtop!!!!
