All FXR models are rubber mount, Shovel Head or EVO, the R in the designation signifies this, early EVO FXR versions use the exact same frame as the earlier Shovel Head.These are for FXR 1984- 94 so am guessing that it's the solid mount not rubber mount model.
So I just found on the same site they do some to fit FXST 84-99 which also fit FX 84-85 so think I'll go for these. Bargain price too...FXR Exhausts OEM Font pipes have a kink to raise the silencer, the FXR rubber mount models have a shorter power train than the FX four speed models which can be seen by the a longer primary chaincase.
