Default Series 2 carrier question?

What would be the cheapest way to put 3:42's in my series 2 carrier? I have a 99z28 with 2:73's. Would it just be cheaper to swap the rear end out for one?

I was going to just buy some used 3:42's and slap them in, but it seems like that's pretty much impossible - how strong/reliable is the shimming method to make them fit well?

Thanks for the help,

Grant

Dont buy used, first off. New gears arent much over or under $200.
I nice install kit may run you $70

Unless your car is putting out over 350+ RWHP, I dont see any reason to swap out the rear, I think your overcomplicating this upgrade.
Check out the sponser " driveline solutions " on the right at the main Ls1tech.com page, I am asking the same type of question in my thread " 2.73's to 3.42's right in this forum.

Buy the right gears that fit for you carrier, with a nice install kit.
Have a shop put them in, and tune your PCM for the change.

If you don't want to swap out your carrier, but "thick" gears, which are 3-series gears made for 2-series carriers. Don't run a spacer.

It may be beneficial and cheaper to search for a low-mile stock rear end out of a M6 car, cuz they're 3.42 equipped.... that's what I did.
