I have 10 each 1-3/8" 16 gauge U bends for sale. $11 each bend. I purchased these from Stahl Headers when they closed for much more. USA made 16 gauge (0.065" wall) bends with about 6" center to center (3" Radius) measurements. The bends are not smashed oval like a lot of the cheapo import stuff now. These were shop stock, and spec'ed by people who actually built nice headers! Has an oil film sprayed on that has dried and turned brown in some spots but can be cleaned off easily. Price is firm
