Just installed the mustang cruiser two piece with no backrest. What a difference and I was able to find it online for about 325. Worth every penny. It is such a deep seat that the back passenger part actually creates a lower back rest itself. The passenger seat is about two times the size of the original.
I did my research on all the seats out there and for the price this was well worth it.
You have to remove all the original seat hardware. I have to drop it fairly close to being on the bike to get the right angle for the front tabs to grab ( I have passenger backrest and drop the rear of the seat under the backrest pad to getit flat for insertion). It takes a firm push to get the tabs all the way in then it just bolts on the regular rear seat bolt. I used a stainless washer under the seat mount to spread the load out, the reat mount is slotted.
Was tired of looking at all these uber expensive seats, and decided I could make my own. And did. Fiberglass pan, simulated snakeskin vinyl. No sewing. (Hate having seams make that one area of your bum go to sleep!) I dont think I could have bought one that feels any better.
