Motorcycle Repair: Delkron transmission case 620-299 FXR, bike mike, speed components

Question
QUESTION: I bought a roller project with this delkron trans case installed. Case is totally bare.  What Harley 5 speed components fit this case?  Will FL trans parts fit this case? With so many late model HD owners switching gearsets to 6-speeds I would like to take advantage of the low prices on used late model take out parts. Delkron has no contact for anyone except dealers so I found no help there. Thanks in advance for any assistance you can provide

ANSWER: What year is the bike?

QUESTION: The bike is a custom Santee swing arm frame 1998. the delkron FXR stle case claims on thier website 1990-1994 all compatible gearsets fit. Not much info there is it? Thanks

Answer
You cn fit any of the 5 speed gearsets in there. the only thing you have to be careful of is the mainshaft. If you already have a clutch then you would have to go with the 1990 to 1994 gear set or the clutch wont fit on the mainshaft.
Good luck and happy riding
