axle id help, don't want get wrong lsd...

[Chang-kuao-lo]

'94 pickup 2WD, standard cab, originally 22RE 5 speed manual. now has a 1UZFE and lexus auto transmission, but looks like the original axle with 5 lugs. i want to replace the open diff with an lsd or detroit truetrac, or similar but i don't want to order the wrong unit. i have the axle code off the vin plate, but i can't find a reliable source to decode this, i seem to get a couple of different answers. not looking to change gear ratios or anything, i just want a limited slip. spinning out on wet pavement is getting old.
here's the drivetrain code:

C/TR 8H8/F J83 A/TM A01A/W55

it seems "A01A" is the pertinent number, but i'm not sure if it means i have a 7" or 8" unit. any help is appreciated.

i think i found something reliable: http://www.toyotaminis.com/forum/at...smission-info-all_toyota_truck_axle_codes-pdf

looks like i have a 7.5" unit...

just change it out to a 6 lug axle. i'm sure there is waaaay more options w/ the 8".

8" were only used on the 4wd versions. And the 7.5" was used on the front ifs differential. Please someone correct me if I'm wrong!

it would be nice to switch to an 8" 6 lug rear, but then i have to do something about the front end, and i'm not too keen on having two different sets of wheels on the same unit. life might suck badly if i had to change a flat.
yes, the ifs 4wd front diff is a 7.5", as is the '80-'95 2wd rear, i'm not sure what the difference might be. but it looks like i got something sorted out. eaton/detroit make a truetrac gear driven lsd specifically for the 7.5" 2WD rear. #911A565. the front ifs has a different part #, 911A342.

but only after getting dicked around by bumpersuperstore.com. they were happy to take my money for something they had listed "in stock, ships in 1-2 business days", and then cancelling my order 4 days later due to a "cost/retail internal pricing error" and are nice enough to hold up $600 of my money for an additional 3 to 5 days. not impressed, i would not recommend doing business with them. i hope that "pricing error" doesn't mean they listed a price on line that was lower than they intended, and now are backing out on their list price. because that would be uber-sleazy.
