Yes I went with the Rally 1000. They are comfortable with nice side bolster even for a bigger guy. But I have not used them long enough to comment on performance. They are definately not a high end seat by any means I'm not suggesting they are a cheap seat but I would suggest looking at them in a store before buying. I don't think it would be that difficult to modify, but the tracks supplied do not have alot of material to work with. They are as basic as can be. That's why I am considering using my original tracks. The seat is a flat bottom so hopefully the mounting holes will line up. Unfortunately I had to leave for work so I did'nt get time to play around with a fit.
