i put a set of 2nd row seats out of a suburban in one of my sqaures, looks alot like what you have. Unless you are pretty short you won't like them.
They set to high and too close.
I cut all of the factory brackets off of the burb seats and welded a piece of 1/2" sqaure tubing to the frone of the seat and then bolted that to the stock track. On the back i welded a piece of round rod from one track to the other and then welded the seat frame to the rod. The tracks bolted to the floor with the stock bolts.
With the burb seats cut down as far as they could go they were still too tall for me at 6'.
Good Luck.
