Ron,
The $200 was for a mustang axle with factory LSD - found it on Ebay, local
seller. Same axle was used from 79-93. Later models might have disc brakes
and ABS sensors.
The $635 broke down like this:
Labor:
$125 shorten housing
$175 gear setup , R&R posi clutches
$60 weld 2 sets perches
$30 bore top perches, turn nuts for bump stops, weld in
Parts:
$109 overhaul kit ( bearings,axle bearings, seals, crush sleeve)
$40 perches ( 2 sets)
$48 clutch pack and friction modifier
$15 big pin for posi ( recommended change from small pin provided with
clutch pack)
So the total got me all new internals, professionally set-up. I could've
save a bit by doing the gear change and setup myself, but you know how time
goes....
Here's a good article on changing gear sets and rebuilding the clutches in
the 8.8. http://www.corral.net/tech/drivetrain/gears.html
If I had been building the "R" with frequent changes in mind, I'd have
chosen a different axle. Several buddies tried to talk me into a Ford 9"
for that reason, but that would have been way overkill, not to mention the
sheer weight.
