I decided to go with Mr. Mikes leather seats from my 355 kit and am very happy with them.

Sure they are not cheep, but the leather quality is great. I also got some seat heaters off of eBay. I just finished installing the seat heaters and leather covers tonight. I can say that hog rings suck, but to the job. The seat do not look 100% OEM, but are close enough. The best thing is to sit in them.
