Body/floor/interior rivets and rivnuts

[voucht]

Hi,
Thanks to all of you for the replies and very useful informations. I now have a very nice smooth black powder coated chassis, and also received the body kit from Equinox. As it has been said here before, the quality is very good.

So, I think I will go for 3mm rivets for the floor, 50mm spacing, same for the trans side panels and back seat panel. And, I don't look forward to this, but I will fit all the body kit elements with rivnuts, as most of you say that it has to be easily removable. As well as the top gearbox and propshaft covers.

Question: for the floor, should I use steel rivets (aluminium will be too weak?)

I'm sure I will have further questions when I start

Thank you very much.
