{"product_id":"motor-mount-frame-spacer-front","title":"Motor Mount Frame Spacer Front","description":"\u003cp\u003eFront motor mount frame spacer will allow installation of a Knucklehead or Flathead engine in a 1948-1984 frame.\u003c\/p\u003e\n\u003cp\u003eThe mount holes measure 3-1\/4 inch center-to-center.                          *NOTE: The spacer is 5\/16 inch thick to make up the difference in 1948-1957 Panhead frames. Knucklehead frame front mount surface is 5\/16 inch taller than panheads. This is the fundamental difference between Panhead and Knucklehead frames. History: Early chopper realized early on that the Panhead engine did not fit in the Knucklehead frame  so would dent in the seat post tube for clearance of rear head. Actually only the front of engine on Panhead had to be lower. Many Knucklehead original frames ruined in this way.\u003c\/p\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e V-Twin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eV-Twin Part Number:\u003c\/strong\u003e 31-0475\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e B-6525\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Engine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Group:\u003c\/strong\u003e Engine Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Mounts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1948-1984 FL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMeasurements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOverall Length: 4-1\/4 inches\u003c\/li\u003e\n\u003cli\u003eThickness: 5\/16 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease verify fitment before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"V-Twin","offers":[{"title":"Default Title","offer_id":47496934195284,"sku":"31-0475","price":37.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/0122\/9908\/files\/31-0475a.jpg?v=1786536051","url":"https:\/\/skywaycyclesupply.com\/products\/motor-mount-frame-spacer-front","provider":"Skyway Cycle Supply","version":"1.0","type":"link"}
