Pair of.020 oversize Pistons for 1941 to 1977 Harley Davidson 74 in big twins. Bought a box of these when Dixie Distributing went out of business. You can see part number m11229 on the box and you can also see that that is 020 oversize. These will fit shovelheads panheads and knuckleheads 1941 and later. I believe the last year is 1977 because I believe in 1978 they went to 80 in as the standard engine size for the big twins. Please note that these do not come with the Rings. You must purchase those separately on your own. Please check our listings we might have rings for this listed elsewhere. Keep in mind that this is older inventory and there may be some oxidation that needs to be cleaned off and the boxes aren't going to be perfect condition.  Please note we did find more of these but they are wrapped in newspaper.  Please note you may get 2 in boxes or you may get 2 in newspaper.
