Update Time
Finally got the rear end installed after figuring out all the measurements (with help from forum members, of course
)
So here is what I have done:
Ford 9", narrowed it myself, had a buddy do final welding
Ridetech 4 link installed, I used nuts and bolts instead of the cheesy self tappers for the majority of the connections. A piece of wire welded to the nut worked out great to get the nuts in place inside the frame rails.
98-02 F-body rear brakes installed; figured out a 2.5" offset works well for them. I should have used the flush mount GM ends from Moser instead of the standard ones, but removing .105 from the rear of the backing plates solved that issue.
On to the pics:
