FXRS frame compatability

I just joined up and cant seem to find this topic so here it goes...
i have an opportunity to buy a 1990 crashed FXRS cheap, the engine and most of the rear of the bike is very nice. I am thinking of just buying a frame and replacing the needed parts, i would like to stick with original harley frames to avoid that custom build hassle. The problem is I am having trouble locating a frame for the bike, I am wondering what frames if any are compatible to swap with this one? FLHT of the same year are available on EBAY but not sure if that will work.

The issue with the FLHT frame is that the neck for the forks extends waaaay forward, may be OK if you plan on a FLH forks and fairing. I'm sure there's other little things that may be different. For example, I replaced my frame with an FXR frame from the factory, my original rear master cylinder didn't work because Harley changed the rear brake mid year in '87.

FLHT won't work for rebuilding an FXR.

Lots of changes to the frames year to year, so lots of part numbers. The main things to worry about is the rear master cylinder mount and the steering head stop. With that said, for you it shouldn't be a big deal. Sounds like you'll need trees and forks, so you can go either way, early or late style.

Be aware that you'll need a title for the frame you use and you'll need document the engine as the numbers won't match. Old title transferred to your name will cover that. Also some states get real picky about salvage scooters and mismatching numbers, so check it out before you spend a lot of money.

Lots of used FXR frames out there, but no easy way to see if they are straight. IIWY, I'd be looking for an 88 or later frame and a 39mm front end. Always remember that FXR's share parts with Sportsters. If you ask the price on a Sporty front end, it's one thing, same piece for and FXR is another. FXR's tend to bring a premium price.

Good luck
