Okey doky, your mention the standard and dealer installed heaters, I thought we were talking about the "Deluxe" heater. I may be mistaken but I thought they were all the same..
Beleive it or not all the guys with Advance Design arn't regestered Stovebolters. I would say that I run into at least one person a week on the street that has one or knows someone that has one. Talk to many more at the meets and surprisingly very few know about Stovebolt.com and a lot of them have never heard of VCCA. There have been attemps to document how many AD's are still registered but I doubt if that would be possable. One thing for sure, there are a lot of them left out there. I you figured that only 1% needed a replacement heater core you would eat them up in no time. Of course these are only opinions on yours and my part and taint worth dickering over,I give, you Win!
I'll still make up a drawing of mine when I get it out just incase I get all may projects finished and need something to do.

Woody, I took a good look at those pictures, great shots. Looks like a 3" four row copper core. Two rows are covered by the inlet tank and the other two by the outlet tank, both are the same shape. The bottom tank which looks to be nothing more than a brass flanged box and just covers all four rows. I'd like to check with a radiator shop and see if they could get four row cores that were 8 1/2" tall, width wouldn't matter, it would be easy enough to split a wide one to make a few cores.
