I have 1 seat available that already has the MG/Ujoint fixed seat base installed. It's two tone light gray/ gray. I've had this mounted in my van on L-Track for ~15,000 miles and used it to hold my toddler's car seat. Condition is good to excellent. There is one plastic tab on the side covering that broke off when I was installing the base, but it doesn't affect the seat at all. Only reason I'm selling is because I bought two new ones that don't match this one...
I'm asking $500 and would prefer not to ship. Located in Denver, but I can possibly deliver to Utah in the coming weeks.
PS: Forum member Ebflow has the matching driver side seat for sale. This would make a complete set for someone!
