I've never dealt with that particular booster. However, I did try to replace my original Bendix from my 1968 Charger and what I was sent from Cardone was no where close to looking like the original, but was functionally the same. I suspect what you have there will work fine.
So, I sent my original Bendix booster out and had it rebuilt and installed it. I don't like the looks of substituted parts for the original. I think cores are drying up so Cardone is using what is available. If looks matter to you have your original rebuilt. Otherwise, what you have there will probably get you going fine.
