Never thought about the BMF. That would make it look real good.
By the way guys, I did not mean to fully fab the buckle with brass. I thought just maybe a groove cut with the back side of a knife on each side with a dab of brass paint in each slot would do it. Sorry, I guess I should have been more specific about that.
Either way it will still look great. No one ever goes as far as to put the shoulder harness in these cars. Or, at least none that I have ever seen.
