    Two different length ARB drop links!

    Well it seems that the more time I spend with the parts for the restoration of my 1966 911, the more I realize that the Factory made a lot of changes on the run. . . I have to check the parts book, but it looks like there was a change in the length of the ARB drop link along the way! Check these out!

    Both are 901 343 076 03. . . I think. Have to check the old book for a different number.

    I sourced some LWB hardware for the ARB, presuming it was "identical." Does anyone know which is SWB and which is LWB? I suppose I could figure it out from the amount of "droop."

    It DOES provide a measure of adjustability, though! One long link and one short to dial out the preload. . .

    Two different length ARB drop links!

    John, I'll try to remember to measure the ones on my 67 since they're off and handy, tomorrow when I go to the shop. (this something I certainly wasn't aware of )

    My SWB parts book shows a 901 343 076 01. LWB book shows a 901 343 076 03.

    Ed, that would be excellent, thanks. I'll post the center-to-center length on Sunday.

    Harvey, thank you very much for looking it up, that is a big help. Now I just need to figure out which is which. I have new bushings and steel inserts ready to go.

    Thanks gents! Stay tuned for more mysteries as I turn a big pile of parts into a running car!

    Next problem, my 66 and my 70 measure about the same (Approx 8 3/4 C to C). (Upside down with a yardstick in the dark) Hope you have better luck. My 66 had sways added later so they may have used the late ones?

    I have no problem with the theory that all men are created equal.
    But after that moment you are on your own and nobody owes you a damn thing.

    The ones that came off my '66 are 24mm C to C. I have another set, of unknown origin, that measure 23mm C to C. I never noticed they were different.
