Air-Flow Seat Cover fitment?

Hello! I recently purchased an Air-Flow Seat Cover for the GT. Initially it seemed to fit well; however, I can see where the "fabric" can potentially chafe the painted areas of the fuel tank and rear fender. Additionally, after attaching it the strap across the front of the pillion is now no longer to be able to be reattached. So, if like me, you have the Triumph tail pack you're out of luck. Anyone encounter this and come up with a remedy? Something like an aftermarket strap to fasten around the pillion and provide an attachment point? Also, with it fitted, I don't seem to be able to exert enough downward force on the seat for it to engage the lock.

Any ideas are appreciated!

Verify if your straps are underneath the rubber spacers that are on bottom of seat that rest atop frame...reposition them other than over rubber pads....seat should clip down now.
