I bought this 1995 camaro z28 a bit rushed, I am not sure if car has the spider gears welded or if it has a locker, well anyhow I was wondering how much it would cost to put in 3.73 gears and what brand I should buy, I don't really want to put a lot of money into this. I really do not know much mechanically of cars so keep it simple for me haha car does have 3200 stall

 

probably looking at 300 bucks to setup and switch gears

 

What makes you think it may have a locker in it?

 

Do the rear tires go chirp-chirp-chirp in the turns, to make you think both wheels are locked to each other?
Your rearend originally had a clutch type of limited slip, which has no spider gears to redneck-weld together.

 

every turn i take you can feel and hear the tires skitching, real easy to see in gravel.

 

Before you decide on doing anything then, you're going to want to pop off the rear cover and do some exploring.

 

well I'm thinking the gears are welded, so if they are will that be a problem for me? I just want the car to run smooth, not really a fan of driving the car with posi the whole time, i don't like the skitching around corners

 

look around for another 4th gen rear end, 93-02 camaro. if you want limited slip (posi) find a z28 unit. do you have traction control? if so you will want a traction control rear end. if not you will need a non traction control rear end. either tc or non tc will work but you will lose traction control and have a tc service light.
other option is to find a center section and have it installed. you can try and install yourself but its not easy and cost for failure is start over with a rebuild or whole nother rear end if it goes to pieces. cost for whole unit from a wrecking yard should not be that much. cheaper than center section and install at a good shop.

 

what does a z28 rearend go for in a junk yard? I have no idea :P and it does not have traction control

 

In order to do that, the original limited slip carrier (has no gears to weld) would have been removed, an open diff section installed, and the gears welded. Or, perhaps someone removed the original carrier and installed a spool. Both of which would be senseless moves to make for a street driven car. Again, you want to remove the diff cover before trying to diagnose what you have to avoid any guesswork, the same as how a surgeon would do an exploratory before diagnosing an internal sickness.
