I converted my 68 Camaro to a 3 speed TH350 transmission and am having trouble finding a seal for where the detent/kickdown cable enters the transmission body. I have read that there is a tophat shaped seal that will work but I can't find it online and the seal that NAPA came up with was too large. The seal that I need will have a 5/16" inside diameter to fit the cable housing.
TIA, Mike.
