Good Afternoon:
I may be able to help you out and I am fairly close to you.
I have a pair of running v-12's (in cars) that I am restoring and lots of spare parts including blocks.
Have been driving my Lincolns for a few years now. They are great cars.

Oldrelics: I am in Canada too. I got my buddy Gerry to pick up a case of GL-1 at NAPA in Palm Springs. In Canada NAPA doesn't sell the same things as they do in the US. Anyhow, simple solution, reasonable price.
