    Almost forgot about this, just some general info.

    As most know, the accepted way to get VSS with a 205 (for an electric speedo setup...driven off the case, not a speedo cable) is to use a later 241 setup and adapt it to the 205 output shaft/housing.

    Anyways, I pulled the "sensor" out of the '91 205 last night, and happened to notice it looked like a sensor I pulled off another transfer case...one that was sitting in an S10 in the wrecking yard. (small GM case, obviously not for fullsize) I compared to the two, sure enough, almost physically identical. ONLY difference is the little metal "nub" that "reads" the toner ring...the 205 one is either shorter, or just ground down a bit (perhaps from slight output shaft slop?) than the other one I picked up.

    Dunno if it helps any or not, but may be a cheaper/more plentiful donor source. (who knows, toner rings may interchange too)

    Not really.

    Cable driven setup it's just easier to use the speedometer mounted VSS.

    Personally, I'm sick of the cable being "bouncy" (which screws with the ECM) but going electric speedo adds its own complications...again the transfercase issue, plus the DRAC, and associated wiring/ECM issues.

    VSS is a requirement for TBI systems to run correctly.

    Notice I didn't say run, I said run correctly. Just use it in the first place. No reason to sacrifice driveability for an hours worth of time. (installing it)

    Cable driven VSS is an extremely simple setup.
