I have been cleaning my seats to assess what work they need and have a few questions.
1 - What is the preferred / best option for seat diaphragm? I am not going for originality, more comfort and reliability.
2 - What year did the seat brackets change from rivets?
3 - What is the cut out on the drivers seat for? I am new to early mini's so am still learning.
4 - I hope to unpick a section of fleck and the piping to replace, is there any reason I cannot that I have overlooked?

I love a bodge, I thought this seat looked quite puffy!

Thank you
