Here's the thing about the Ford 9". And not trying to talk you into it, this is just my story. A friend GAVE me a 9" out of a 1970 F100. Gave. Scott free. I cut the housing ends off myself with a large tubing cutter. They will make perfectly straight cuts. Then I took it to a friend and gave him the stock A body flange to flange width and he narrowed it to stock A body width and welded the Mopar housing ends on. I already had the housing ends left over from a project from years ago. So now we have a total of $100 in the rear end. My friend Matt down the road pressure washed it, sanded it down, epoxy primed and painted it RED. No charge, because I always help out with stuff here and there when he asks. After that, I got a 4.11 ring and pinion from Summit on sale for $129 bucks. I already had A body backing plates. I got A body brake shoes from OReilly. I have a commercial account. $11 more bucks. I rebuilt some A body wheel cylinders. $6. I got a Chrysler 8 3/4 brake line set from somewhere....Inline Tube.....Summit.....Right Stuff, hell I don't remember. It was like $25. All I have left is the pair of custom axles for about $500. So, that'll still be less than $800 for a complete Ford 9". That's well under what people are wanting for a complete 8 3/4 AND a stronger rear end with MUCH more available service parts. There's no down side.
