I have a 96 contour with 5 spd man trans and the shift selector shaft seal is leaking.I thought no big deal,I removed the old seal and went to autozone for a seal,but the new seal has a bigger outer and inner diameter.It is loose on the shaft and to big for the housing.I tried the Ford dealer and he told me the part I need is not available.Any ideas?
