    Cressidas that had lsd are rare, and was part of a sort of "sport package" that also included a 5 speed manual and motorized adjustable rear shocks that switched from comfort to firm dampening. They could also come with a 4.10 ratio rear diff as previously mentioned, so best to either read the data plate on the firewall or get underneath and count the turns of the driveshaft.

    So if I understand this right, you want a lower ratio for your truck than it has now to give it more grunt and still keep the highway rpm's somewhat tame? Is the truck auto or 5 speed? Automatics usually have a higher overdrive gear than manuals, so that and tire size could help determine your ideal ratio.

    Since the truck is a 22re, have you read about the Supra AFM upgrade? You can use only the 82 supra AFM and directly swap it over, plug and play, to increase the airflow into the engine. It's the only year that the signal voltage transition matches the 22re afm; all other years are exactly the opposite and won't work. This makes 82 supra parts even harder to find. The igniter is also a one year wonder and is one of the likeliest parts to fail, making it the hardest part to find.

    A friend of mine that owned a Toyota junkyard started out with a 1987 Toyota 2wd truck that he used to pull a car trailer hauling cars home from the weekly salvage auctions. He named his truck "stretch" because it was a metallic gray extracab longbox with the 22re and automatic with a column shifter. He worked that truck hard, but still took care of it. He replaced a blown head gasket at 140,000 miles with a Toyota head gasket that never blew again. He upgraded the front brakes to the one ton brakes. He redid the box 3 different times because it would rust through (patched it first, new box sides the second time, replaced with a solid used box the last time). To make a u-turn required careful planning and either a 3 point turn or running over a couple of curbs. He sold it with 450,000 miles on it, and last he knew the guy who bought it had 570,000 miles on it, still on the original engine and tranny. Awesome truck.

    I saw a pic in another thread of your truck. You do NOT have a longbox; in fact Toyota never made an xtracab/longbox configuration from 89 - 95. You might have to double-check your axle code because you might have the more common 4.10 gears already!

    lots of canadian mx73 cressidas came factory LSD, hard to find a open diff. both my supras diffs are factory LSD, as is my mx83 cressida. Canadians got that "benefit" with whatever packages they were selling back then.

    they're all crap though, unless you re shim them with new clutch discs, but even then, can only do so much..depends what you want from a locking diff

    Didn't realize they even came longer than mine. It's a 6 footer. And yes, I've been scratching around for an 82 AFM...I have ONE but I need it elsewhere LOL.
    I am NOT actually looking for a different ratio for the truck. Just the parts to give it limited slip.

    Lexus IS200's, Altezzas or whatever you guys call them have 7.5" open and Torsen diffs in them, and are a lot newer, Casings different obv.
    As someone whose had a ma61 LSD apart
    > http://driftoy.proboards.com/thread/...-strip-rebuild

    I can tell you that to do it properly it costs a hella lot in parts and bearings and seals to rebuild a Ma61 lsd, and to start with you have to have a really good condition diff, and it's best left to the professionals when setting up the backlash ect, so include labour for that. If i was to do it again, i'd not bother and get a KAZZ diff, as you can't really get away from the fact that the kazz is superior in terms of response and sheer number of clutch packs over the pissy amount in the toyota. Click the link ^ and you'll see whats it looks like all stripped down

    Ooh, I bookmarked your build thread already, so excuse me while I investigate your advice

    edit - hmm, seems KAAZ makes Supra diffs, just not Mark II. Which one are you thinking, Altezza?

    edit 2 - dude, thanks for the tip on the Lexus stuff, I am already finding options available for the same $$$ as 34 year old parts...

    Low on details and ships across a pond, but...

    That 4 bolt pattern looks awfully familiar. There seem to be lots of these out there. Has anyone else done this swap?

    I looks like you need to swap out the attachments or do the entire assembly to me.

    NO ONE has discussed this,that I have seen or read,so far.
    How is it different and what are the advantages?
    I see no top "brace". Maybe the out drives have the same bolt spacing.
    IS 200? Really?
    How many IS 200's are out there and what years does it include?

    I'm gonna dig into this as much as possible before I move ahead, that'd be a hell of a resource for all of us if it can be done somewhat easily.

    The externals are different on the lexus as i stated earlier, The internals are what i thought was what mattered as they are newer, and you have a torsen option. It's a F series 7.5" diff, Kaaz part code is SAT2090 -http://www.driftworks.com/kaaz-lsd-toyota-lexus.html
