Vacuum Amplifier 3671424 / aftermarket equivalent
 

UPDATE: BOUGHT PART, BUT STILL WONDERING ABOUT AFTERMARKET EQUIVALENT
Just bought a 1974 B200 Sportsman Maxiwagon van with a 360 -but now I can't find a vacuum amplifier....
there are a few NOS on ebay, but not sure how age might affect these things -and they are not cheap!
I know Borg-Warner made some aftermarket vacuum amplifiers for old Mopars, but I'm not sure which would replace the 3671424.
Any help with finding the right part or a workaround would be much appreciated!
I would be interested in a NOS part if not ridiculously expensive!
