I talked to RDS. They have the regulator I need but his advice is to get a complete set of doors.
What I have is an early NAS door that came from a 93 110. Looks like Im better off buying a rusty, dented, junk door from a NAS 1993-1994. It should have all the parts I need.
By the time I buy all the pieces I need new, Ill will have paid just as much as buying a good set of used doors.
