Decent looking project. Looks like a 72 coupe.
Rallye doors are pricey. I normnally see them go for around $300. They are a 1 year only thing. You'll also find that the bulge hood is VERY pricey and so are certain trim peieces.
BTW DO NOT get rid of your C pillar charger emblems! They are a 1 year only thing and VERY hard to find. Originals go for big $$$.
The fender lights are also unique for 71/72 chargers vs. the 73/74's.
My buddy is working on a 72 rallye we trucked home this year. real 400 2 Bbl gold w/ black top.
