You are purchasing a complete USA made lower engine mounting hardware kit for UL ULH big twin flathead or side valve engines used from 1937 to 1942 or early 1943.  All bolts are correctly machined plain head.  This kit includes the special motor mount nut and lock, used under the generator land area as well as three 3/8" castelated nuts with cotter pins. All bolts are machined exactly as Harley machined them on their own screw equipment back in the day.  This is for the lower mounting parts only, we sell a complete kit with the top hardware on another listing.

We offer a CP-1035 & CP-1038 UL motor mount kit on another listing for those of you with a 1943-1947 model UL.  We do have the 1948 only front motor spacer, but still have not put together a correct kit for 1948 owners, please check back if you need a kit like that.

We also offer every piece of hardware for your UL including bolts in plain head, CP-1035, or CP-1038; round and fillister head screws, wire harness clips; cloth covered brake, throttle & spark coils; cloth wiring harnesses; Linkert carb parts, brake parts, etc. etc.

Please see the "Vintage Hardware Pre-1980" section of my eBay store for different motor mount options as well as other CP-1038 and CP-1035 hardware kits. I also have motor mount kits for U, UL, ULH and 45 solo and Servicar.

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. Top mount bolt and all 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" including a CP-1038 gas tank and oil tank mounting kit which would go great with this.
