New in Oregon

Hey everyone, I just bought my first Goldwing. I got me a 83 interstate, has 80k on the clock, but has maint. records out the kazoo including head gaskets, timing belt and waterpump. runs like a top and rides like a dream. Ive been looking for a couple things though, if anyone has an answer it would be awesome.

To really be comfortable, I have to sit on the back of the front seat, kinda the hump if that makes sense, was wondering if they make a seat to fit that riding position.

Second is do they make a replacement rubber for the markland floorboards.

Hope to get to know you all better
Paul
