Just like the old post says - INDY DRAG MAGS . Back when I was a pup here in Indy we called em INDY TEN SPOKES. Were out of my price range then and still are.
yeppers..Indy Drag mags...and your lucky to have the centers...they are available in repro, but are pricey...Ric from Ric's custom polishing in Monessen , Pa has tooling to repop the centers, as well... they are a nice 60s touch.
