These wheels came with a car i bought a year or so ago.
They were known as 'slot mags' in the UK in the 1970's, don't know equivalent here in the USA .... I don't know what make they are but i'm sure someone here will !!
I have no further use for them, so i hope that someone can find them useful.
They are not the lightest but are in good shape and are drilled for 3.75" (Triumph) and 4.25" (Ford) PCD.
They are 5.5x13 (of course) and have a backspace of 2.5".
They use shouldered type nuts.
I'm looking for $400 but make me an offer
