At the moment, on my 64 Cutlass, I have 14x6 super stock II rims from a 66 442. In one of my various part deals, I traded some Olds stuff for another set of what I thought were those same wheels. I noticed the other day, they have "chevy" written on them with paint marker, and stamped on them, the codes: <b>14x6 JK and then below that M4.</b> they are solid chrome all over, except for the black painted portions of course. I'm in the process of doing a disc brake swap on the 64, and tried them over the 70 malibu spindles & rotors, and they fit! the Olds rims do not clear the calipers. I've got some 16x8 GTA rims, polished rims with black centers, I'm putting on the car, eventually, but I'm taking the car on the long haul on the power tour, and could use the $600 for the tour, rather than bigger tires for now.

Any Idea what this rims are off of originally, based off those codes?
