Well, I think now I know what the rarest E body part is. It's a manual choke bracket that bolts onto the rear carb on a 71 Carter Hemi AFB. This is what the cable bolts onto to operate the manual choke. It's so rare, I don't even have a good picture of what they look like. I'd hate to hear how much it might go for as I need one. I know that there are other super rare parts out there also. So what do you feel is the rarest part not being reproduced for a E body? Any others?
