Hi, sorry I did not respond to you last year when you sent this. I have not been on the board for quite some time until recently. You probably by now have figured out a solution but I used a Chrome Pro-One Slimline Oil Filter Adapter. No other mods except lengthening oil lines. It was a very tight fit as the front header tube fits tight against the engine case but it does work. Once again I apologize for responding so late.Ride safe..Scott
I noticed you resolved the same issue I am currently having. I have forward controls on my 99 FXR and also wanted to fit TH 1019s. When you used a slim oil filter mount was that the only modification did you have to do? Nothing to the pipes? Also, witch mount did you use?
