I have a studded wheel flanges to bolt my 16"PSE wheel and tire to. There is a large Allen bolt pointing out. I'm figuring that big Allen bolt holds the out side studded wheel flanges to the half shaft coming from the inside of the upright hub The tires and wheels are off on both side of the car. My upright hubs inside protective bells are not altered The PSE wheels cover the Allen bolt when installed
I see your ERA Jag IRS already has the 45° zerk installed. The picture looks as if there may be more room in your upright bell than I have in mine. But you see what a difference a 45° zerk makes. I'm not going back under for a while but I swear my U-joint cross is different than the one pictured.
I started the "what would change " thread This one of my concern that I just got stuck on.
