hey i just put a 3.27 9 bolt rear in an auto camaro (1991 700r4) that originally had 2.73 and was an open rear. can someone tell me which speedo gears i will need for my trans? i know that there is a tech article on this and im not trying to be lazy, but i just would like to know from some one with more knowledge then me in this area rather then me trying to figure it out and end up with the wrong parts. thanks for the help...
