I am going to a junkyard saturday and really want to find some lower differentials I have a 1996 geo track 1.6 16v 3 spd auto. I believe I am running 4:20s stock I really need to know what vehicles have direct match differentials with lower gears .

Find a sidekick/tracker witha 5 spd.  91-96 i believe have 5.12's....  if you can find a 89-90 5spd, those are 5.83's.  the auto's have the 4.6's or whatever. 

Yours has 4.30s in it now.
For the front, you will need a 96 and newer third (sidegear spline count changed in 96).
For the rear, any 89 to, at least, 98 trackick will work.  If you have rear ABS (a wiring plug on the thirdmember housing), then you need to find a rear third that has a plug.  If you don't then it doesn't matter, you can use a third that either has the ABS plug or one that doesn't.
Better look at this link to determine what gears are found in what vehicle conguration.

Read my list on the first page and then stop.  All pertinent info in that thread is contained in my list on the first page.

Sorry guys idk why I keep writing 96 I have a 95 1995 what yrs and trans and body style should I look for to get bolt in 5:83s

Look for the gold plated ones, that's about how rare they are!  Sky is correct, you have the 4.30 ratio if yours is a 95 auto. Any 5 speed manual thirds ( 5.125)  will bolt in giving you plenty of gear for bigger tires, up to 32's.

There are no factory 5.83s.  The lowest factory ratio is 5.62.  I have a set that will work in your 95.  But they are not cheap.

The 5.62's you are thinking of only came in the 89 Kicks with then 1.3L sami motor in it... Find a carbed 89 kick that still has the diff's in it and you've found the end of the rainbow.

Yes, that is correct.  But finding one is very unlikely.

I have 5.83s with lockers setup in the 3rds I'm wanting to sell PM me if you are interested
and yes the 5.83s are gold plated as well as well trained, Moab 3 years and other fun places,
pricey but well worth it

I also have a T-case with the 4.24 low range gears and it also slip yoke eliminated, you have
the option of using a SYE or stock driveline
