OK guys I've been going crazy trying to find something on this radiator, the one noted above and searching all over the internet for 3 days trying to find one or one that was close enough to work. I don't know if I can look at another radiator on ebay. I have found out they were made apparently by Thiokol out of Logan and at some point NSN parts sold them. The manual list the number as 0106022 and NSN lost their number as 2930008906338. Sure would appreciate the guys that have these replying with what they have done when needing one of these or what one they used. I guess the last resort is to have it recored but as I looked on line it appears they could cost thousands.
