Oil cooler by-pass

[7007v6buickman]

What other vehicles used these. Where can find a new one

What exactly are you asking about? The oil cooler adapter that's attached to the oil pump cover?
I know the Chevy 4.3 installed in trucks and vans used one BUT that's a completely different animal from the Buick 3.8

To by pass the cooler all you have to do is remove the adapter between front cover and oil filter.
