Complete upper and lower engine mounting hardware kit for OHV engines used from 1936 to 1957 on rigid frame springer and Hydra-Glide big twins- this is what we call our “generic” 36-57 rigid kit.  As the bolts are CP-1038, they would be "correct" from roughly 1948 to 1957, but will certainly work for any '36 to '57 big twin.  This kit includes the special motor mount nut, lock, and lock washer used under the generator land area from 1936 to 1957. The top motor mount bolt is machined exactly as Harley machined them on their own screw equipment leaving a small tit at the center of the bolt head. Flex-lock nut on top mount bolt is commonly associated with 1948 to 1951 models.

If you aren’t hung up on bolt head details, this is your kit.  If you are aiming for the most authentic restoration as possible, here are our other options we offer exclusively:

Please see the "Vintage Hardware Pre-1980" section of my eBay store for different motor mount options as well as other plain head, CP-1038, and CP-1035 hardware kits and bolt sets. 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.

A note on shipping:


Please understand sellers on eBay do not set the shipping rates.  Please also understand that sellers are charged a final value fee on the amount of shipping you are charged over and above the fees they pay on the sale and the Paypal transaction.  In addition to that, sellers have the expense of labels, shipping materials, padded mailers, etc.  I do charge a handling fee on some items, but I also offer several shipping options whenever possible to give you more affordable shipping choices.  If you ever think the shipping fee charged is too high, please let me know before leaving a low rating on shipping charges.  It’s rare that I receive such feedback, but I work hard to keep my customers happy.  I’d rather know if someone is unhappy before they leave a low rating.  That’s the only way I can solve a problem.  I don’t ever want a customer to go away unhappy!
