Best source for Recaro seat bracket?

[Jon Linkov]

I've come into a nice blue recaro seat for my '83 (thanks Neil S!), which I
plan to use initially as a driver seat and then as a passenger seat when I
get a true "racing seat" later this year.

Unfortunately, the Recaro was used in a 200tq, so I need to source a seat
bracket for the UrQ. Any help on this is appreciated, as it's my first
replacement seat in any of my cars (n00b on seat swaps).

Thanks!
Jon
