Just to add a little more. The '01 cobra had 31 spline inboard shafts also. The '99 is the only one that didn't.94 Daily Driven 4.6L said:My personal recommendation is to get one from a Cobra (pre-supercharged, but with the IRS – supercharged Cobra’s have 31 spline half-shafts), a Mark VIII w/traction lock, or a T’Bird/Cougar w/traction lock.
I have T/A and the FRPP unit. With T/A on, I floor it, the car launches like a mofo. With T/A off, car launches like a mofo. I can't really tell a difference with it on or off. When I had the open rear-end the difference was huge.94 Daily Driven 4.6L said:
If I disable traction control I leave two black marks when flooring it from a dead stop

Expensive tires help alot. As long as it's above 45 out, they hook up very well. I run SUMMER tires in the summer and snows in the winter. BIG BIG difference in the performance of a summer tire vs a all-season.94 Daily Driven 4.6L said:So you're saying that you can't spin a wheel with it either on or off?!?

I am not trying to cause problems, but I pulled my axles out with no problem. I changed nothing. They "popped" in and out just like my factory on did. Maybe I am just lucky, maybe. I just know I have a 97 stang trac loc with a load spring out of a 4x4 truck.Rich95XR7 said:Man, I've posted this quite a few times, I have done the swap, and here is the EXACT differences.
The IRS Trac-Lock has a BEVEL in the gear, not a slot. It is there to make it so that you can take the halfshafts out of the car without dissassembling the entire rear. You can put the solid axle Trac-Lock in the IRS with NO RETENTION PROBLEMS, because the circlip will slide all the way past the gears, and expand. Where you run into a problem is when you have to take a halfshaft out for some reason. Without the bevel, the circlip will not compress itself and slide out, which leaves you 2 options, pry hard enough to break the circlip (not really an option for me!) or take the cover off the rear, and pop the circlip off with a pick, and then pull the halfshaft out. There are NO safety issues with running a solid axle trac-lock in a IRS rear, and it will not allow the halfshafts to slide around.
