You are purchasing one USA-made parkerized front muffler pipe clamp kit for 1941 to 1973 45" solo and Servicar models including G, GE, WL, WLA, WLC, and WLD. Stamping and parkerizing detail is restoration correct on the clamp. This clamp was introduced in 1950, but any of the reproduction exhaust kits don't typically include a front muffler clamp even for the earlier models. Bolt and nut are machined identical to H-D's process they used from the 1920's to 1950's, nut is machined with the flat land on it. Hardware is spot-on for the originals. Bolt is plain head machined and is the only style of bolt we have available for this. I have no idea if this was available as either a CP-1035 or CP-1038 bolt at any point during the original production years. We offer each clamp individually with mounting hardware and offer this entire kit with either plain head or CP-1038 marked hardware. Comes with the following parts by OEM number:1037-50 (New# 65275-50) Front muffler pipe clamp074 (New# 4289) 5/16”-24 x 1 13/16” bolt, qty. 10261 (New# 7045) 3/8" split lock washer, qty. 10127 (New# 7793) 3/8"-24 x 21/64" x 9/16", qty. 1Please double-check your reference material to make sure this is to be used with your model year and exhaust type as there were so many different variations over the years. We have other variations on 1930-1984 exhaust clamp kits with correct hardware on other listings in our store. If you don’t see what you are looking for, just ask.

If you ever think the shipping fee charged is too high, please let me know before leaving a low rating on shipping charges.
