Torsen Differential

So I had some good luck at the junkyard last weekend and found a 2003 Ranger FX4 Level 2 which came stock with a Torsen differential, of course it only came with 31 spline axles, but nice find. As I was thinking of going to 5 lug axles anyways, has anyone used any of the aftermarket companies; Strange, Moser, etc to have some stock length TC axles made? Even if I went the SN-95 route for the 5 lug axles, I would still rebuild the factory traction-lock which would run me $150 for the kit, figured axles shouldn't be much more than that for 31 spline, 5 lug, stock length. These from SummitRacing look to be very close to our length, 29 7/8 vs 29 15/16, fair price, and 31 spline. Thoughts?

Moser and Strange both make good axles. I personally would not by anything other then axles from Moser. I have never been impressed by their assembly practices when it comes to complete axles and differentials. The Summit axles are OK and would probably work on most of these cars if the length is right. How close are they?
We never used the Summit axles on high horsepower cars but for a stock replacement on nearly any 8.8 application they should be fine.
I think the Torsens are better then the Ford trac-locks so if you can get it cheap enough I would consider it an upgrade. I would not consider either one if buying a new unit. If I were buying a new differential I would get a Truetrac.

I already have a 31 spline Torsen diff pulled from a 2003 Ranger FX$ Level 2, so it was cheap. The axles I found at Summit are the Summit brand ones, 31 spline, 5 Lug and measure at 29.937 long. Compared to the stock 88 TC axles which measure at 29.88, the Summit brand axles are 1/16" longer than stock. even better are the Strange axles, 31 spline, 5 lug measures at 29.910 long, which are only 1/32" longer than stock. These seem like the best fit and may even fit with the stock calipers and parking brake set up in the 88. I realize the 2.3 turbo is not a huge torque monster and the Torsen is probably way overkill for it, but I have one, and want a 5 lug conversion anyway, so this might take care of both.
