I drove them for years. The CVPI rear end is an 8.8 and the diff is plenty durable but the wheel bearing and axle units are very weak in the later models for whatever reason. I think it's also a bit wide for a Mustang application unless narrowed, and if I was gonna go to that trouble and expense I would just spend the money on a good 9", 8" or an Explorer 8.8, in that order.

I'm not looking to swap the entire rear in, just want to take the disc brake set up off and add it to my 67 rear end.

 

I couldn't swear to it, but while the 1998-2011 body is the same, sometime around 2001 or 2002 they changed the type and location of the trailing arms and moved them further outboard (big old aluminum control arm) and the brakes probably had to be redesigned. I think there is an Autoguide forum on the P-71 / Panther platform cars and the swaps that work and don't would be easily searched on there.

 

None of them are easy or simple!

 

I hear you there. I guess easy and simple are relative to the guy doing the work.
For me, the afterrmarkets look straight forward as do the late 90's CV. Pretty much bolt in but not much mention of 2003 and later or PI being of simular "ease" or what it will take to make it work.

 

You can swap in 11 inch finned drum brakes from a Crown Vic. It is a significant upgrade and the parking cables clip right in.

 

That would be good if I were going with drum brakes but looking to swap to disc. This rear end came along at a great price so if it’s a feasible disc brake swap, I’d like to go that route.

 

I've put 94-04 Mustang rear discs on a couple cars with the factory 8" housing. They're easy to get up and running really good. You could probably find new ones for around $100. I've bought used for as little as $50 a pair.

Found your site and see you have a kit available. Based on your pictures it appears backing plates will not work with your kit? Also, did you ever get a parking brake solution put together?
