Question about 340 dart hood scoops

I recently purchased a set of hood scoops for my 1971 valiant. The description said they fit coronet/super bee and duster/darts. After I purchased them, I ran the part number and discovered different part numbers for each :banghead:. The ones I bought are part nos. 2949194/2949195 (1969) and the other ones are 3443130/3443131 (1970-1972) So my question is; Does anyone know if they're the same size?. And do they think the 1969 set will fit my 1971 valiant? Thanks for any help.
