I used Auveco 808 clips and the bottom rail support. Small angle brackets with nutserts on them for the armrest, then ran a 10/32 through the bottom of the armrest to attach the armrest to the door.
I will have to look at that. I there a reputable source for seat heaters? I see them selling for anywhere from $39 up to $500 a heater. What heaters have installers have good results with?
Thanks for the comments! I will have to look at both of those options when I get the truck in. If I can find a place to put the switch out of sight that would be easiest I believe.
