The adjuster bar for my drivers seat has detached itself from the seat base again ☹ Is there a proper fix for this? I can get it to go back in with lots of swearing and fiddling about but after a couple of adjustments it comes away again. It’s alright for me as the seat is set where I want it, but worried it will be a fail come mot time if the seat won’t move ☹ Thanks in advance for any help 👍🏻
