seat question: what fits stock 1981 FLH (FLHC)

Have anyone had a close look @ the Yamaha Star Bolt seat?
here's one for sale (http://www.ebay.com.au/itm/Yamaha-St...item20f5ddbb29)

Wonder if this seat could be modded to fit a stock 1981 FLHC ?

While on this subject, there's a lot of seats available for newer HD's, but not that much that would fit my FLH and year
Most pics never show what the seat look like underneath so I'm having a bit of a struggle figuring out if any newer model seats could be slightly modded to fit my bike

- In short: Is there any newer model seats that could fit (even after minor mods) a 1981 FLH?


Primarily looking for comfy *big ass solo frame mounted seat like Dany Grays or similar *(alternatively Silhouette style sofas) that would work with a swing frame on my stock FLHC while preserving nice esthetics / lines


The seat I currently use is very similar *(if not the one), to this one http://www.ebay.com.au/itm/181831401...%3AMEBIDX%3AIT
