71-74 B Body Rallye Cluster Wiper Switch & Headlight Switch

[VegasCharger]

Anyone know if they're repro's on these switches? The external piece that has the blue rim on it more importantly. They seem hard to find used. If they do show up used what can I expect to pay for them 

Thanks

I have some numbers for you Bryan.
Wiper switch is as follows:
3621668 2 speed
3621672 3 speed
Knob 3488265

Headlamp switch is the same through all the C bodys (not E or A).
3514427 switch
3488276 knob and stem

NAPA has the light switch, NG on the wiper.
Knobs would be a swap meet item.  Which one do you need or both?

Bryan.
I have 3 spares.  Will include one in the same box gratis when we work out the vacuum tree mystery.
