I know my 64 Spider had LH/RH lug nuts intially but my mechanic must have changed the LH lugs to RH and forgot to tell me about/or I forgot and thus ordered a set of LH lugs which I can't use.
Please note both LH and RH lugs have to be custom made due to length and their about $15 a piece but look very nice as they are polished stanless steal
