Not as far as I know, but it is just a $100 housing from a Ford pickup, so who really knows. No tube-to-housing welds. I brought the pictures down to Bob Lambeck since I had to go by there anyway, and he said run it. The conflicting/angled patterns show that this set may be impossible to get "perfect", but it is well within the acceptable range as is. I'll still measure the housing as Bob George suggested.
