there's a reason bypass kits come with 1/2"or bigger hose-volume, volume volume! you couldn't get enough oil through an existing port, like the oil pressure switch. the 1s i've seen for domestic applications come with 1/2" pipe female threads. a good bit bigger than the 10 or 12mm hole you might have in mind. and so it goes, chuck.

HitManX was right on.
What is needed here is a partial flow filtration set up, it uses a small line to sample off the full flow filter, usually at the oil pressure sender to gradually remove contaminants.

Surely there must be room for the aux filter somewhere under the hood on that big S-body?

Pssst! has anyone got a bypass filter adapter (full flow, to remount the filter) for a W115 chassis (gasser or diesel) if so please Email me! I've been looking for one for 10 years. They do exist, an aftermarket thing.

What in the hell are you talking about? The OP is talking about a piggyback bypass system like this:

Go ahead and scroll to page three and four to look at the sizes of the fittings. So there goes it, chuck

i wasn't aware of the amsoil kit, my bad. i've always seen the full flow kits. don't know the benefit of a piggy back bypass system, have to look into it. thanks, chuck.

Replacing the suspension bushings in one of these old cars (or something like that) will actually accomplish something. Installation of an aux filter won't.
