Default Re: Trans identification (year)

The 15/29 set is OK for light body car with a 3.54:1 rear axle ratio. The 16/28 set works well with the 3.78:1 ratio in about any application light or heavy but will run higher engine rpm at the same speeds. The Lincoln gear sets were used with 4.11:1 or greater ratio rear axles and many Lincoln car transmissions had the overdrive but the inputs and clusters will fit the 78 case.

As long as it has a 78 series case, it will fit anything that was made to fit in there.
