Aftermarket buckets and brackets
 

Ok I have a little bit of an issue here. i am trying to put in some aftermarket seats in my truck. The seats only have mounting holes on the bottom of them to mount to the frame that was provided. The frame itself is a one piece contsruction that ties both seats and the console together as a unit. The frame is also angled to provide the typical seven degrees used on seating. My problem is, I don't have any brackets that allow the seats to slide back and forth, up and down etc.. Does anyone have any ideas what I can use. Are ther any aftermarket brackets out there?
I can't ask the place I got the seats and frame from because they no longer make them for our style trucks anymore.
Thanks
