Anybody know who makes these seats from my Blazer?

[wildmanaaron]

Here are a set of seats that were in my Blazer when I bought it recently. I dont think they are original since the bottom frame work/bracketing/mounting is "aftermarket looking". They just dont look original. The floor brackets are original style Blazer though.

For some reason I remember seeing a set like these in someones catalog before, but I don't remember. Can anyone tell me who made them or what they may have come out of?

Any help would be appreciated!
