You can buy a C&C the qaulity is great, I have 1 of these jobbies on the old superglide.

they sell through parts pro.
(you can of course buy from states and save 40% but I didnt tell u that).

Failing that get a local trimmer to do your new seat in a custom style, personally I reckon this is the way to go.
 

How much for 48??? What colour did you get?? Have you seen the aged leather look e.g. CVO Fatbob below? Just an idea....
