I'm running a 1352-146 (1985 S10) 4.03:1 1st gear, 0.76:1 5th.
As far as I know, 1986 was the last year for mechanical speedo drive.
I've got a sheet I printed off years ago from inlinersinternational.org. Can't bring up that info on their sight anymore, maybe someone else can post the link. I've got another one stashed (not wanting or trying to sell), 1352-145 that is '85 - '86 S10, has 3.76:1 1st & 0.72:0 5th. I like the 4.03 1st, but I'm an area with terrain. If you find one & have a tag # I'll see if it's among my listing.
