I have an '84 S10 Blazer with a '99 frame, I have cut the whole floorboard out and done a full body drop. The frame sticks up too high in the body. If I build a floor over it, my seats will be too high and everything will be off. How do I remedy the situation???

Can't seem to find a driver side power window switch for my 87 s10 blazer. 2 door. Anyone know where I can find one/order one from?? I've already exhausted all junkyards in my area. Thank you
