Does anyone make a spring solo seat that will fit a 91 FLSTC?

 

There is no shortage of solo seats selling on EBay and Amazon that are made for spring mounting, and that may fit your bike and your butt. The challenge however is rigging your bike so seat has a base to mount to. I did a quick search for you and came up with this:

Some bobber builders just buy the desired seat that will fit their frame (length and width) and then fab a metal pan that they can weld on the spring mounts and the front seat hinge mount. All this takes a lot of skill, tools and time to do right. I almost finished mine, build for a bobber I was building, but I sold it before I was finished (had the pan cut and the seat bought).

Google search images using this phrase, 91 Harley Softail Classic solo spring seat and see what you find. A lot of hits come up so you'll have to choose what suits you.

Good luck.

 

And it’s not just the seat and mount it’s hiding all the stuff that’s underneath the seat that’s now going to be exposed.
