I would imagine if the fenders,hood are interchangable the 70 bezels and grill could fit. I'm curious why you would want to use 70 bezels instead of the 73? The 70 are very expensive and hard to find ( I've been looking for a pair myself) 1970 headlight bezels won't work if you are still going to use the 72-74 grill. If you replace the whole grill assembly, any year will fit, wiht the proper bracketry. 1970 bezels are being reproduced now, but grills aren't, and they are considerably more expensive than 72-74.
Not a single one !....the 360 cu.in.was not available in a road runner untill 1974.
The bumpers for a 1972 Plymouth will fit a 1973 Plymouth duster with a little fabrication.
