To be sure of correct application this custom kit fits any of three serial number tag designations from CP that have letters: "A", "K" or "L".
This 2" long extended anvil is USA made with all materials mined here. CP makes their tool parts outside the US and under different hardness specs. My anvils are slightly harder than OEM parts. There is a shoulder that is machined onto my anvils to hold the hammer cam release spring.
NOTE: My photos show 2 sets of o'rings for this kit that I offer. In some cases I ship red silicone and buna 70 o'rings. In more current production I am using both sets of buna black rubber. Silicone has become cost prohibitive and is being exhausted from my inventory. The mix of either both of just buna is based on my dwindling on-hand stock. Your kit will continue to have 2 sets of o'rings based on my choice and not necessarily what is shown in the auction photos.
The shipping weight is 1 pound with a USPS Priority flat rate envelope, eBay label and tracking. International buyers have this item shipped to Glendale Heights, Illinois for the eBay Global Shipping Team to finish the delivery and customs paperwork documentation.
