need help with holley 750 d.p

What kit is that? Do you have a link or part number? In almost 30 years of rebuilding these things, I have not seen a kit that comes with bushings as of yet. I am aware that bushings can be had seperately from the aftermarket but Holley does not consider this a service item.

There not bushings really (i should have said strap seals), thats only if the base is worn, then you need to drill & install bushings, what i'm talking about are the factory "nylon" strap seals that wrap around the inner recessed parts of the shaft by the throttle bores & outer area.
