OK.
Only had 3 hours today to work on the car.
I was able to rip out the old 6cyl rear end, and wheel the new 8.8 under it.
Looks like I might have lucked out. I was expecting to be a hair too wide, and was planning on slitting the rear quarter flare and pulling it out an inch. Looks like I might get away with rolling the lips (after installing the new quarters of course)
Anyway, I know a thread is worthless without pics, so here we go.
Old rear coming out. Right side front leaf spring eye snapped off when removing the bolt through it.
Old and New (new will be painted before I am done of course)
Trial fit
Apparently a full width Explorer 8.8, 18x9 wheels with 6.18" Back space (30mm offset) and 275/35/18's is almost a perfect fit on a 66 Mustang
