Looking for a used 1 : .7466 ratio adapter to correct speedo from TH400 swap . Rather than having to go into the trans tail stock to replace drive gear . Because I would need a 48 tooth driven gear to correct the problem . and a 48 tooth gear is unavailable . so I would have to change the drive gear .
* actual Radar Gun speed is 45 km/h - speedo reads 60 km/h . *
GM has a 1 : .7333 ratio adapter that was used on early Chevs . GM# 3932220 that would work as well . The 1 : .7466 was avaiable from Stewart Warner . The perfect ratio adapter in this case would be a 1 : .750 but that would more then likely have to be custom ordered .
