Paul, these seats did look very cool... May I ask where did you source them ? I'm planning to adapt similar ones custom made in my GTD. This could save me some time.
Hi Paul,
I've been remiss in not responding. Here's how they turned out. I'm still trying different combinations of foam but they turned out to be a pretty good fit.
Pierre-Louis, they appear to have been fabricated as a one-off from an upholstery shop. I don't think they are a factory product. That's how I had the seat base fabricated.
