I have a set of steel rims off my 69 Hemi RR. I purchased the RR back in the early 90's. need help figuring what these are 2 have the big H, has 15x6 JJ made in Cana.a stamped on inside, 1 has small H with the 15x6 JJ and made in Canada stamped on the inside, the other has no H but 15x6 JJ made in USA stamped on inside and has numbers by the valve stem, 3641331, all wheels have the 3 nubs to mount the hub cap. I think the 2 rims with the big H are 69 Rims? the small H is 70? rim, the other no idea, looking for help and info. thanks and be safe
