so i just recieved my super bad ass driveshaft from an LS1TECH sponsor and guess what. yeah it is fucked up of course. the slip yolk has 28 splines on the new one and my old one has 27. so the question is.......... do i have the odd ball out of the bunch with the 27 spline output shaft or did i get the screws put to me by them sending me a 28 spline?

i hate my luck

it is a 2000 camaro ss by the way
