91 FXR engine swapped into a 97 Road King

I just bought a 97 Road King that needed an engine. I ended up finding a 91 FXR engine to swap. I pulled my motor out of the road king and noticed the mounting for the oil filter housing / other parts were different. What’s the difference between these to motors? Is there a lot involved in making it work?

Check the breather fitting on the rear of the crankcase just inboard of the oil pump, is there enough room or will it hit something?

It looks like I have to reroute the oil filter housing to the rear. There isn’t any mounting holes in the front

FXRs have the oil filter under the frame, right in front of the back tire.
