yeah i aint seen any parts guides for sale for my model yet
but thanks for the info
Parts Catalog for the 1954 thru 1978 Sportster is part number 99451-78B. Get it from the dealership or order it from J&P Cycles. It's pricey but like said before it's the best money next to the Service Manual you'll spend on your bike.
Trying to think of a really good signature
