Just my "" here ... Those so-called "police wheels" with the oval-cut slots didn't appear on any MoPar police car / fleet / taxi , until 1977 or 1978 ; same deal with the "vented" hub caps .
Prior to 1977 , steel wheels destined for police / taxi / h.d. use were 'simply' 14x6" ,15x5.5" , 15x6", 15x7" , and later ( mid-70's ) 15x8" , and had a ring in the hub centre which was stamped "HD" . The 15x6" variations were used exclusively on the 1969 1/2 Road Runner / Super Bee with the 440 6Bbl / 440 Six Pack cars , which are well-known as the gloss-black-no-hub-caps-chromed-lug-nuts wheels .
While those wheels look great on any rear-drive MoPar , they weren't available from the factory on anything other than "B" Bodies ( 1977-1978 Monaco , et al. ) , "C" Bodies ( 1977 Royal Monaco , et al. ) , "F" Bodies ( 1977-1980 Aspen / Volare ) , "M" Bodies ( 1980-1988 Gran Fury / Diplomat ... Doc's favourite cars ) and "R" Bodies ( 1978-1981 Gran Fury / St. Regis ) .
Okay , now I'm just being ostentatious with my opinions ... I'd venture to say that the versions in the why-did-Monogram-drop-it 1970 Road Runner would be your best bet , and would look great on your Gee-Tex .
