Barry, I think you got. I looked at the codes on the radiator. One number was 46M. Under that number there was the number 3113455. So.... I assume that I have a 46 radiator (month of misery?) in my 39. Is that the way you read it? You are one of the few people who has possibly seen these two different radiators side by side. What kind of differences are we talking about? They can't be to different. Unless someone is interested in an even trade, I think I'm back to modifying the mounting flanges. So much for thinking that I at least had a good radiator.

Many Thanks for the help,
