I just purchased a HZJ105 with rear jump seats (3rd row is perpendicular to 2nd row). They a simple fold down "bleacher" like seats. I found that CruiserParts sells lap belts for them, two per seat. But they can send me any pictures of the belts until they I pay and they then pull them from the LC. I've had a slow response from them so far, but will try to synchronize time zones Monday to call during business hours for more information.
I'm worried I'll have to do some crazy fabrication to get hem to work, but at least that would be better than doing a total seat swap.
Has anyone ever seen the rear lap belts it a jump seat 100/105? I'd like to know what I'll need to do to get them to work before dropping $200 on them. I live overseas, so I'll have to have them brought over, so I want to make sure they are what I'm needing.
