Graham,I have looked at most H.D FLHT 91,92 & 94 frames on US ebay. One breaker/dismantler contacted said that 89-98 EVO/FLHT Frames are interchangeable. Not too sure if that info is correct. Bungo.

around 95/96 they lowered the seat height and inch so that info is not correct

Bungo, various things happened mid-life with our Evos. One is they went to a longer swingarm, although the earlier shorter one will fit (I swapped my early short one for a late TC long one). In addition the seat mounting changed, however one of the most important changes is doing away with the oil bag, when engine oil was moved to under the trans. It would be simplest to get one from the earlier years IMHO, just to minimise any snags that may arise.

The "breaker/dismantler" is wrong about fitting up to the 1998 models. True, they all had the EVO motor. But the first major change to the frame happened in the 1993 model year. Beginning in 1993, the oil tank was moved under the transmission. The rear brake master cylinder was moved about 3 inches forward, but still inside the frame. This change was made to make room for the oil tank and lines from the oil pump. if you get a frame, don't get one from 1993 to 1998. Your 1991 is different.
I speak from experience and manuals. grbrown will back me on my knowledge.

I am talking about the frame Only. You can use a frame from 1979 to 1992. All parts from your frame will bolt to the frame without any modifications.
