Hi everyone, I am new to the forum. I am currently involved in a major restoration of a '71 MGB. (My first MG) My question is: Do any of you know where I can find one of the little "pushbutton" retainers that keep the seat belt end bracket from being able to slide back and pop off of the mounting bolt on the rear deck? It has a light spring under it. One side is fine, but the other side is broken. I have not been able to find one in any supplier's catatog. Thanks for any info on this. Carey
