Opps,you're correct on the speedo.I'll dig up an earlier S10 tailhousing.The mechanical speedo drive gear can be positioned on the electric speedo Camaro T-5 mainshaft with careful measuring,shimstock and good old JB Weld.I believe the speedo gears where Saginaw parts adapted to the T-5.There's also an adapter to convert electronic drive tranny to mechanical,but it's 300 bucks.
