Should definately be the exact same length. I installed mine with a PB, and the installers would have noticed that they had to muscle those puppys in to fit.
Hey I have also noticed a clunk in mine going into 1st since I installed the MM LCAs. I'm going to measure my arms because it was a pain to get them in there and we did notice they were slightly longer than stock. Thanks for posting up the correct length now I can compare and post up my measurements tonight.
