Vacuum switch for Columbia Rear End

[29FordRoadster]

My brother-in-law has a Columbia overdrive in his 29 Ford roadster. He uses a vacuum switch from a 1948-49 Chevrolet ton and a half truck two speed switch to activate the overdrive. He is in need of a new/used switch and has been unable to find one in local junk yards. Does anyone on the forum have such a switch or any leads where one might be obtained. If additional info is needed on the switch, I will post more tomorrow after talking with my brother-in-law. Any leads or help on this will be greatly appreciated

Thanks Bob C. that article was really helpful by listing sources for parts. Also thanks to Castlenut who had a vacuum switch just like what we needed and he is willing to sell it. I really appreciate the willingness of the people on this forum to help others.
