First of all, the fixtures and lenses should be made by Cibié. These will have three screws through the front and the manufacturer's name is visible in a couple of places. Earlier cars have lenses by Hella and there are only two screws. I don't think Canadian market cars had different fixtures than US market cars so I'm thinking you have the later Cibié fixtures.

I have a set of these and the sockets are integral to the housing. Only the contact, insulator and wiring are removable.

When you say, "They all have the offset pins," is that based on just looking at the bulb? If so I think all you need to do is get the bulbs I mentioned.

What bulbs did you remove?
