I need a measurement please (engine bay)

the passenger side inner fender changed starting in 72 and up. The later style is supposed to give easier access to the alternator on a slant six with the presence of a charcoal can.......so to be the same inner fender you need to measure a-body car 67-71.


I only know about the difference because I was going to replace an inner fender on a car one time and I had the different style from a parts car and when I noticed the difference I had to go and find another parts car with the same inner fender. They all weld up and function but if your like me then a difference like that will drive you up the wall and I would have to end up re-doing the whole car simply because of a small difference like that #-o
