Bezel Differences?? WTF????

[79BIG10]

I know the bezel changed from in 79 with the bottom of the column trim piece and then also in 84? when the wiper control moved from the bezel to the turn signal column. Now here's my dilemma- I installed the new Autometers in the truck with a bezel I got off a member. He didn't know what year it came from but looked like the one I had. Only difference is that the new one has a extra back trim piece around the edges where my factory one doesn't. It's a small piece of trim like it slips into place into the off green style inner bezel but when I mount it to the truck the trim piece that is different on the new one hits the dash itself where it won't mount up right. Looks like I'm off to a junkyard unless anyone has any ideas on how to fix this?
