Nice work Dave,
I wish I had heard about the Danish Oil treatment before you first mentioned it on an earlier thread.
I had the seats out of my car last year as I wanted to get a slight backward tilt on my fixed seats. I created new battens with a slightly more exaggerated incline by raising the front of seat. Luckily I can still get under the larger wooden steering wheel! I wanted to drop the seat a bit as I am a bit of a 'tall lad' and would be nice to be further 'in' the cockpit but on investigation (and pre-advised) the intrusion of the rear spring housing would not allow this unless modification to the underside of the seat.
Looks like I will have to have them out again to 'oil' the floor in the Spring now!
