I will need to look for pics of my 73-71 duster 340 LOL. I changed the grill HS style. made it fit. it had a tunnel ram, auto W/ stall converter. Keystones. and was the best I could do in HS. but a 6-71 Blower was on my mind. so I was close but it was a few years later that this happened. and it is the Hemi I still have in my HS car 1969 Coronet R/T.
