I looked a little closer and I think there is a difference between the Canadian models from the US models .I looked back and found that out of the buckets I have 3 were purchased off e bay and at the time my buckets were still on the truck .so now that I have them off you can see although they look the same the inner circle protrudes farther out .The black one in the picture is the US type and the green is from a Canadian truck.So what I did was I used the headlight holder and trim ring from the Canadian version and they are deeper and that is we’re it became a problem .i found that I only have one holder from the US bucket and they look like they will work .I guess if you need to replace your buckets on a Canadian truck you will need to get the bucket with the light holder as they don’t mix .the holders pictured are greyUS and black Canadian
