Just thought I would throw this out there for anyone interested. I have a 04 Ultra. The stock seat was miserable so I bought a Mustang. I had it two days and sold it to someone else. I thought it was like riding on a flat board. Next I ordered a dual Corbin. I had one on a RK I used to have and liked it just fine and looks great, but my wife hated it and she said the same about this one. I sent it back. Next I read from another site about Diamond custom seats. This one was on the bike for about a year. I had to do some modifications to the backrest and to the pan to make it fit the bike right. It is not bad and the wife liked it but I just did not like the looks or the fact it is covered in vinyl. It made for a hard ride to Sturgis this last year. In fact I bought a AirHawk just to have on the way back. Now all that being said.... I bought a Russell Day long seat. It is leather seating and it fits like a glove. I wish I had done this in the first place. Attached is a picture. Ultra 04
