Hi, Love your Duster, similar to my 71, may have some questions for you particularly re: suspension and guages, both of which need extensive work on my ride......
I forget the backspacing on the wheels. I will try to find out. When i first got the duster there was a pentastar on both sides of the fenders but i removed them and never put them back on.
Looks great! Got to ask though, is there a penstar on both front fenders or just the passengers side. Lost my D/S fender 25 years ago and can't remember.
