Brave man! But who knows, it’s definitely been a few years. And given that price point I definitely get it!
Yes, I measured both the AFCO’s I have on my Duster and the oval tracks I have as they both have the longer front section. They were pretty much the same, I don’t recall the exact measurements but I would definitely remember if they were a 1/2” different overall. And with the AFCO’s the shackle angle was correct, which is the more important part anyway.
