Does anybody know how difficult this swap would be and what's involved?
I have 66 coupe with 289 and stock rear.
thanks

I'm not sure what the width difference is. That would be your main problem. If it's just a little off, you could just play with the offset of your wheels. If you have to narrow it, it will start taking some real effort and money. You would have to narrow it,and get new axles for the custom width. Either way, you will have to move the spring perches I am sure.

Think about doing what I did. Google "used Cougar parts". There is a place in Washington I think that has a ton of donor Cougars. I got a 9" that bolted right up for cheap. No modifications at all, except I put taller gears and a traction lock in it. I haven't found an easier, more economical way to do it yet.

I agree. I am not good with welding so i will stick with bolt on changes where possible.
I'll look for 9" as you mentioned.

that width won't work...

95-01 explorers will, but you'll need to run more back spacing, such as late model 17" wheels.

don't be afraid to modify stuff. take both rears out, bring them to a shop, and have a shop weld on spring perches to the rear using the same measurements as the old 8"

I think the flange to flange distance you need is 52 1/4". F-150 has the larger wheel bolt pattern.

Sorry, I should of explained a bit more. The one that I found is not from F 150... I understand that i cant use F150 rear end because it's too wide however as V8Only said explorer rear end can be used with some modification.

I found this 9 inch rear end locally and I do not know where it's taken out from but i know that the distance from backing plate to backing plate is 57". I think that distance is matching original 66 coupes so I hope somebody can confirm that and if this one would work for me or at least let me know what I should look for when I go to see it. I have original Magnum 500 wheels from 72 mustang.
I do not know what the gear ratio in it is but that's another story for another discussion...
:cheers
