FYI, I have a Del Sol Drivers seat slider assembly modified for bolt up to any flat bottom seat (Kirky seat), in the garage. It bolts to the stock mounting points. $20 plus postage and its yours. Its a pro fabricated piece, probably costing me $100. Unfortunately I put it in my Sol and found I was sitting to tall so now we are bolted straight to floor.

I believe the Sol and the CRX seat mounts are the same, It's floor mounting hole areapprox 14.5" front to back and side to side between mounting points.

Word of caution though, any height above 5 - 10 and you start having helmet hitting roll bar issues. You can email me [email protected]
