AutoGear The newer mustang IRS is supposed to be a pretty stout unit; although it won't look as good fully dressed out as the Jag, it probably works a zillion times better.
I rode in a Jag equipped Tbucket and I was less than enthusiastic about the ride quality over say a 4-bar setup or coilovers in the same style car.
That being said, I have no idea about the skill set of the builder of the car. Perhaps he had the whole thing FUBAR and I didnt know. I imagine the flyweight Bucket vs the hefty full-bodied Jag has something to do with it.

late model IRS

I saw a t-bird IRS too and to me it looked like a lot more work that using the jag. I'm like you, I like the way the jag looks too, especially when it's going to be fully exposed.

late model irs.

I saw a bird IRS in a T bucket about 7 or 8 years a go at a car show. The guy said he was going to fab up tubular control arms and sell a kit but haven't seen anything yet. the stock pieces look too much like minimum cost stampings 50 years ago the brits were into function more than minimum cost when they designed the Jags. . The jags always looked better under a T bucket. (4 jag IRS and IFS in the shop for our projects.)

I have seen the Corvette, T-Bird and other IRSs. I chose Jag IRS because I have two of them and I didn't have to go searching for another one.
I may regret my choice, but for now, I'm going with what I got

lmsport The Trac-Loc diff in a solid axle and an IRS are the same. Just need to get either 28 or 31 spline to fit your axles. Both diffs are available from Ford for less than $300.

sounds like a win

Thanks for all the input guys
Cobalt a wealth of knowledge about getting a limited slip in it...Thanks

I'm thinking this is gonna be the way to go for me. Affordable strong and easily adaptable. Might even detail out nicely with the cast aluminum lower arms.

Time to grab the tools and head to the old pic-n-pull

Hahaha good call. I'd honestly hate to have to do anything other than regular maintenance after putting it in. The fact that they make a kit for it is very cool, a PI SOHC or the DOHC 4.6L would make a miata a real screamer.

That must be a heck of a squeeze. Even the 4.6 sohc in the Mustang is a tight fit.

LATECH That makes sense . Run what you got I guess. The t bird might not look as pretty when it is all said and done .There is most likely a LOT of them around.
I have owned a herd of t birds in the late 90s and a few cougars. Never had trouble with the rears. The supercoupe I had had the 8.8 and the axles were the larger size compared to the v-6. IIRC the v 6 could have the 7.5 or the 8.8 but both had the skinny axle. the supercoupe and te v8 cars had the 8.8 and the thicker axles. Just thought it was worth the mention.

For one thing, they are a work of art when detailed out, and back in the day they were about the only game in town AFA having anywhere near the strength needed to handle American torque.

It is possible that they were just the ones that everyone used at first and it became mainstream. Even though something else would work well and was easier to come by. Kinda like the mustang II front ends dominance of the industry.

Crosley Many of those IRS are the 8.8 ring gear as I recall.

We used the IRS in a mid engine sand rail back in 1998... a SB-Chevy with a powerglide hooked to the differential yoke with only the u-joint and slip yoke into the PG.

LATECH Mark vIII are pretty much a t bird- cougar from 89-96 - 7 -?
lots of stuff bolts up. I had numerous birds -cougars. Was allways gonna get a wrecked mark 8 and put the powerplant in my bird. Then I decided that a pickup was a smarter choice.

joe_padavano I suspect these are related to the T-bird IRS, also plentiful in wrecking yards.
