I put an 09 seat on my 89...and it didn't sit right. The passenger seat angled back, but yours is a "newer" frame than the 89 and it looks fine on yours. Other than it lookin weird it was comfy. I ened up with an 06 RK seat on the 89.

 

I am not sure exactly what year it came off of. I will have to check for a p/n on it. My buddy gave it to me to try out, he didn't know what year it was off either. It does seem to be way off at the tank and it probably is a newer seat...

I also have a seat for a 97-07 and that seems to be much closer out of the box. It appears if I cut a slot in the tank mount/frame it should fit perfect. I tried it as other suggested by kinda jamming it under the tank tab but when i sit on the bike the front of the seat moves side to side and it looks like crap.

Your saddlemen seat looks really good. I like that style of seat. I'd be afraid that if I took the seat apart I'd never get it back together...

 

I just fit a 97-07 Road King seat on a 90 FLHS. I also switched to a FLHR gas tank so no longer had the FLHS front tab that was part of the original gas tank mount. I cut the frame to accept the front mount on the 97-07 seat and drilled the back fender for the rear mount. I'm not sure why, but the seat pan would not properly fit the contour of my fender so I had to take the Dremel to that and cut a bit of the eat pan. This may be what caused Mountainkowboy's seat to tip back at the rear of the seat. I have it fitting well now and am confident that it will be secure when mounted up. One concern to be aware of is that is that the seat, as I have it mounted, is wide enough that it does not leave enough room to pull the side oil bag dip stick/stopper. To add a quart of oil I'll have to pull the seat each time. Not ideal but not a big deal since only one screw.

Let us know how you make out.

 

Actually that was an 09 seat that leaned, the 06 Mustang RK seat I adapted fit with a little modification to the front of the pan.

 

I just took a 97-07 seat apart today and used a heat gun to make it fit along the fender better. Now I have to put the seat back together... that’s the fun part right? 🤣

 

Great idea on the heat gun.

 

Just stealing everyone elses ideas over here
