USA-made fuel or gas tank mounting hardware kit for the 45 and Servicar style gas and oil tank used from 1937 to 1973.  As the bolts are plain head machined, they would be "correct" from roughly 1937 to 1943 or so, but will certainly work for any '37 to '73 45 solo or Servicar.  The bolts and nuts are machined exactly as H-D did back in the day, the plain and flat washers are accurate as well.

Starting in 1943, they would have used CP-1035 marked bolts from Chandler Products and would have transitioned to CP-1038 bolts by 1950 which we do stock in our store.  I believe they used cad plated hardware in the late 1950's and 1960's possibly.  They also phased in other bolt manufacturers in the 1960's & 70's though I'm not sure when.

There seems to be some misinformation on CP bolts and "reproductions".  Chandler Products has always been willing to produce these bolts with large minimum quantity orders. There's either early production or current production. They changed head dies as they wore out and had multiple dies.  Nuts are USA made using the same process Harley used when they operated their own screw and nut equipment with the flat lands on them.  Spacers and washers are produced just like the ones H-D did back in the day.  Parkerizing is same finish as how these came from the factory in the 1950's.  I've also got other hardware kits listed in my store under "pre 1980's hardware".
