Transmission Slip Yoke insertion depth
65 GTO drag car - TH400
My current Spicer slip yoke (casting #C3-3-319) looks to have an approximately 3" long shaft with approximately 1.5" outside the transmission with car at rest leaving 1.5" in the transmission. I have seen a recommendation that there should be more like 3" in the trans and 0.75" - 1.0" of the shaft outside the transmission. Do I need a slip yoke with a longer shaft?
