A/C O-Rings for 1958 Cadillac

[DaveW]

I'm trying to find some parts for my '58 with air conditioning.  I'm trying to find the two O-rings that are located at the interface of the rear of the compressor and the manifold with the two lines coming out of it.  Measuring the size of the groove for the O-rings and compensating for some amount of compression of the O-rings it appears to me the size of the O-rings should be an ID of 5/8" and a cross section of 5/32".  This is a non-standard size.  I can have this O-ring custom made, for a price, but there must be a better way.

Does anyone have experience replacing these O-rings?  Are they round cross section O-rings, square cut O-rings, or some special type with a carrier?  What is the proper size?  Anyone know of a source for the correct parts?  I have checked the online catalogs of Old Air Products and Vintage Auto Air with no luck.  Will give them a call on Monday.

Thanks,
Dave

Dave,
Go to the nearest Automobile parts Wholesale distributor and you should be able to buy either the rings or a kit containing these rings. They are not that Unique for automotive AC use.
