WTB: ignition switch, heater core, heater valve

[osubeaver]

Looking for an ignition switch for an airbag equipped car. My understanding is that there are two types.

I'm also looking for a heater core and heater valve. I haven't check if I have the plastic or aluminum pipes yet, but does it matter if both the heater valve and core are replaced together? Any info would be great.

Car is a 1990 325i coupe.

Yes, airbag cars use a different ignition switch. I believe the non-airbag switch will work, regardless, but it's always best to get the proper part for your application.

I recommend buying a new heater core (they're $100 new or so) but a used unit will probably work just fine. Make sure to replace the o-rings. Unfortunately, finding a new heater valve won't be so easy (they're $233 - IF - the dealer gets any more, which they probably are not).
