cobra buckets

[Jacko]

i am going to (if i keep my car ) look in to getting some bucket seats for it as the front passenger one needs replacing anyway, just a few things really.

are the subframes different for each different type of seat i.e other makes if not are they readily available?

sidemouts this may sound dumb but what are these and where do i get them from

also what happens about airbag ecus and things alike

thanks
