are the LS1 and Lt1 rears ends interchangeable thanks that is all

 

different brakes I believe and thats it

 

different brakes and be sure to get the e-brake cables and the metal line that runs on top of the rearend housing connecting to the calipers you should be golden...make sure the rear you are getting has the sensor on top of the housing.

 

thanks for the info

 

You can't mix the axles and brakes. Use LT1 axles/breaks together and LS1 axles/brakes together.

 

the speed sensors are different i believe also.

 

That's a new one... Wonder what all those people with LT1 10bolts and LS1 brakes are doing I'm sure if I told you we took my 93 disc mounting plates, calipers and rotors, and put them on an 98 S10 10bolt, you'd say it couldn't be done? >_>

The only thing with axles you have to look out for is the spline and length. 4th Gens (and I'm sure the 2nd 1/2 of 3rd Gen as well) can all interchange. Now if you plan to use ABS, that posses some problems. But using 98+ in 93-97, I am working on a solution for that I just have to get my car back in the shop and the rear brake lines installed (not to mention the trans heh) before I can implement it. But considering how the 93-97's ABS work, I don't see my solution being an issue. And you just have to use the 98+ EBrake setup, which is only from the cable-junction back to the wheels and easy to install. Then again my car, or my rear (newer than '99), aren't equipped with TCS.

 

LT1 and LS1 axles are not the same length. That's the truth. Ask anyone that had caliper rubbing issues when they mixed them.
Of course the LS1 axles are totally different on the hub end to accomodate the LS1 e-brake.
I'm not telling you anthing about an S10, because that was not what was being discussed.

 

From what I had read from multiple people, is the length of them was extremely minuscule. Enough that a washer, between the caliper mounting plates that bolt to the tubes, should remedy it. :\

And I only brought up the S10 since I used my 93's disc brake setup on it, along with my 93's posi carrier. The S10s have drums, so everything for the discs had to be swapped. And I mentioned the year since 98 was the first year of the LS1, and both are 10bolt vehicles. That and we're not even 100% sure it's a 98 S10 rear, could be a 99. We just yanked the motor, trans, harness and rear end (because it had 4.10s).

 

Yeah, that is what I am saying. They are different and have to be shimmed or not mixed. The person that throws them on there and doesn't know, will have issues.

 

well here is the reason for my question, i bought some 2 series 3:73's but havent put them in yet. my buddy has a 98 with gears in it already and said i could get it from him a little cheaper than having to pay someone to put them in. he is selling the car so we would be swapping

 

Well, swapping to one for you wouldn't be a problem (like I said I have a 99 or newer rear in mine), but him using yours wouldn't really go over well
