Ali for the Floor Needed

[MikeB]

I have some ali sheet left over from my last build, think its enough to make the back panel and tranny panels.
But not enough for the floor. has anyone got any left overs or know somewhere at a good price.
Don't mind it being a two piece floor.

Also do you have to weld the seat runner mounts in first, have people used a standard spacing for this as at the moment I don't know what seats I'll be using.

Thanks

Mike
