1994 short bed single cab seat

[bracketshark]

I found a brand new 60/40 seat out of a 94 extended cab Chevy truck and want to put it in my single cab Chevy truck. The passenger side seat inside seat mount is to high for my truck, the seat runs up hill to the center. Anybody got or know where I can get a 60/40 passenger side middle mount? They have been discontinued from the dealer. Thanks for any help.
