I Went to Lowe’s and got some 2 inch flat bar.
The bars need to be cut to 41-1/2 long.
Then I simply placed the flat bar on top of the rear seat and drilled holes threw the flat bar to line up with the factory trunk mounts and into the rear seat and that’s it.
The 2015 and older Gem E4 has a weight limit on the rear attachment points. It would require a different engineered type of mounting. Also seat belts would present another issue. Acquiring an E6 is a better idea over the 2015 E4.and older
E4 Vs E6 I guess it’s about how often you drive 6 people. I had a E6 & it was just So so long & cumbersome I would never wanna have one for how we roll. I would take A E4 with a well constructed rear seat All day long and twice on Sunday.
on the 2015 and earlier what you want to do is remove the vertical back seat cushion . There are 2 heavy duty vertical aluminum frame rails . bolt through those to the new jump seat . You could lift the entire Gem from those frame rails .
Does anyone have pictures of the bar stock mounted to the frame? I have test fitted the seat with both the fiberglass cover on and off. Would like to know how people are connecting the bar stock to the seat frame. Also curious if people are mounting on top of the fiberglass cover or directly to the frame? I am leaning toward not replacing the cover and getting a piece of diamond plate to mount in the area behind the seat to cover the opening.
