They are listed in the Haynes manual. I don't have one with me right now, so that's the best I can do. Maybe somebody with quick access to one can let you know?

You have to double the count if you're doing a peg leager. 1 3/4 would probably be 342s.

The closest thing I can find is 2JZ listed for 1982. 2JZ is listed as 3.23 posi. 6JZ is listed in 1984 as the same thing.

how did you find the stamping codes to decode like that ?

well the deal is that i know for sure first digit is 8 and third is Z, but middle is either C, O, U, or J i cant tewll which, its too lightly stamped

obviously rear is not original in the car, or it owuld have been 2.73, and its not seeming like it is 2.73 nowadays, so far anyways, maye im just gonna have top pull the damn cover, i gotta know, need ot change fluid anyways
havent noticed a tag on cover and it has iron drums, so,..
iron drums correct on a 82 T/A LG4 THM200C ?

thanks guys!
