T56 questions

[trailblazr81]

I found a couple places online where I could get a t56 for about $1300. Tho would have to eat the $300 core charge since Im replacing my t45. The problem is these have crappy. 2.66 first gears. Looks like I have to dish out $2300-$2700 for a t56 with 2.97 first gear. Are these just trannies out of different cars or is the more expensive one with 2.97 first been rebuilt with the deeper gear? I want the .80 5th and the .62 6th. Im more into auto-x and open track stuff. I have 4.10's but dont want to loose it all off the line. How can I get a 6 speed and have a decent hole shot without spending alot of $$$. Also I know I need a shorter shaft, but what else must be done to do the swap?

I'm pretty sure the bellhousing bolts right up, but I think most of the other stuff is different. I know there are kits out there so you can do the swap. The shorter driveshaft you already know about, but I think the input shaft on the trans has a different number of splines/teeth (I think), and I know that the crossmember needs to be modified or replaced with a compatible one.

-shorter driveshaft
-cobra pinion flange or a hybrid u joint
-some type of switch for the reverse lockout
-cobra crossmember
-extended wiring harness for the speed sensor

the t-56 is stock with a 10 spline input...you can upgrade that to 26 spline or if you have the viper spec then it already has the 26 spline shaft.
