Is a breakdown of the T56.

Your best bet is an LT1-sourced T56. This has a remote slave cylinder. LS1 sourced units have an internal slave and the length of the input is wrong.
Make sure you get the OE clutch fork, fork pivot and fork pivot nut. Along with that you'll need the bracket/spacer for the clutch slave cyl.

Thirdgen.org has done this swap a million times. Head over there and poke around.

I wouldnt worry about Viper conversions, as a Camaro/Firebird T56 has most of the same stuff, minus the output shaft, which I doubt you'd break.

Any used T56, plan on needing new rings. Triplecone and double cone synchros sound awesome, and they can be...but thats 2 or 3 rings PER Synchro. This gets quite spendy. You'll also want an IRON 3/4 shift fork and new struts and fork pads. Expect the bronze reverse synchro to be shot, along with probably reverse gear. Id also bet on at least 1 speed gear to be wasted, which is probably another hundred bucks. That'll get you started.

Use the assembly numbers in our manual (13-86-000-004 for example). Copy that down and when you go to look at a trans, you can identify the assembly. I have manuals for corvettes and vipers on he site as well to help you decode the tag.

PS unless you're pushing 500 horse and shifting like grumpy jenkins, SKIP the bronze fork pads and billet strut keys
