Rebuilding SUs?

[spunkysandoval]

HOlley makes, or made a rebuild kit for these carbs. i'm going to try and order a set from work. I think the kit is for one carb only. But there is one slight hang up. I don't know the exact carb I need the kit for. The kits change when the carbs id's make the transition from HJG46W-7 , to HJG46W-8. I don't want to order the wrong kit. But at only around 15$ a kit, that wouldn't be a big loss. I could probably return it anyhow.

Does anyone know the exact carb id for the 71 round tops?
