03 04 mids on paughco frame

Am I going to have any fitment issues putting a set of 04 mids in a 99 sportster engine in a paughco frame?

04 mids? it depends on what type of fitment you're talking about. I don't think they'll bolt on. 03 mids might, but i don't think 04 mids will. i'm sure you can make them fit. i hope someone who knows what they're talking about answers this as well. i wouldn't listen to me for anything. good luck, and post up some pics.
