I am in the middle of redoing my front seat and wanted to add an armrest the the middle that can be folded up like a modern bench seat in a pickup. Has anyone ever done this or am I just going to have to make it up as I go? on an unrelated note which master do i need for disc disc breaks on my 78 scout ii? I know its one of the early corvette ones but Im not sure which. I was just going to use my original but its leaking so since I have to replace it I might as well get the right one.
