Bless the Hell out of you! Group: Members Posts: 10,926 Joined: 29-June 03 Member No.: 869	The 914 arms are shorter, the 911 knuckles drag the ground. (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif) Do I know part numbers? Nope. Do I think there is much difference? Nope. Are you just wanting 911 part numbers under there? Another question, are you going to eat that meatball? M

Are there any differences? I do notice now when I do a tight turn in the driveway that my wheels tend to hop. Could be that I just put on some new Yokohama 195/55/15s or my toe is out of alignment. BTW, with the sway bar tucked under the master brake cylinder, I can no longer mount the steering rack protection plate. Should I be concerned about this or has anyone found a way to re-mount the protection plate? Spoke

Spoke, the protectionplate and the "under car" swaybar use the same mountingpoints. Just put the plate in place, then bolt the swaybar mountingtabs to the car

The reason I am asking is because I want to know if the ball joints are different and to get an idea if I may have upgraded torsion bars. I guess if I remove the torsion bar cover I can count the splines and find out?
