You are purchasing one NOS-OEM exhaust muffler clamp bolt for 1970 to, we believe, 1978 Sportster models as our catalog goes to '78 and it shows 1970 and up in our book.  This is shown as being used with the siamese rear dual muffler in the parts catalog, though it may fit other mufflers.  

Bolt overall length is 1 7/8", thread length is 1", threads are 1/4"-28.  It appears similar to the 65332-65 bolt used on '65 Panhead models but we are unsure of the dimensions on that one to compare.

Bolt appears to be cad or zinc.  Finish is original.

We sell many other parts for Panhead, Knucklehead, Sportster, Hummer & other lightweight, flathead, JD, VL, DL, RL, and single models including Solar and Motolamp headlamps, dash panels, ammeters, oil and fuel lines, and complete wiring kits.  If you don't see it there or cimarroncycleworks, just email us and ask.  We are starting to carry more parts for the early models and Sportsters, keep an eye on our space!

Located at and ships from Cimarron Cycle Works in beautiful Cimarron, New Mexico, USA!
