lets talk pros and cons of all trans options available. i had planned on just hitting my truck with a 100 shot of nitrous but just picked up a tvs1900 for it so ill be shooting for just over 500rwhp on a little bit of spray being i already have everything.

i want to replace my driveshaft no matter what i do because this thing is way to long. (1pc and im long bed 2wd). also i dont think the truck will see much track time. I want a street machine and would love to shift it myself for the added fun.

cost of replacement, drive ability, durability of each
