When I bought my 93 Splash it was without the center console / arm rest. All I have is a rotating metal bracket. I went to the Junkyard and found a 60/40 seat off of a 96 ranger that had the arm rest with storage compartments. How do I take this thing off? I popped what looks like a screw cover off of the inside only to find a metal/plastic black fastener with three corners... and will this fit in my truck even?
