Harley Davidson Original OEM Transmission Top.Cast # J-9 and #33-35.I was told this cover was for a 1939 Knucklehead.This top will work and be correct for later models up to 1950.So you could run and match your 1949 Panhead I believe.This is a used top of coarse so Please look at all pics so you know the overall condition,(see all pics).I see a wear mark on the top by where the 2 long bolts go in,(see pic #9).I also see a long wear mark across the raised part of the cover,(see pic # 3).I see no cracks or welds,and the gasket surface looks good.The unit shifts real nice and I`m sure the winning bidder will be happy with this one.Please remember this is a used top and there are nicks,scuffs,wear marks etc.(see all pics).Good luck bidding.Thanks for looking.
