Rick,
I'm attaching a picture of what I started with regarding the seats. Only one half of the drivers base pan was left. The observers/gunners seat is even worse.
You are correct, the rails under the seat are not correct to the Lynx and they will be removed once I have the scissor-lift type base repaired or replaced. The rest of the seat is correct.
I'm deliberately deferring the observers seat until the Lynx is actually running.
I'm quite enjoying your "walk down memory lane", about your Lynx restoration. Must admit that I am glad that the Mark 11 reverted to a conventional system for brakes, accelerator and clutch.
Peter
