I had a machineshop ream my HD8 carbs and rebush them 5 years ago.
I recall they say in the manual that comes with the set that you aren?t
supposed to drill straight through, but drill from both sides and leave some
material.
That took a bit more time to align, but it was possible. He used a reamer for
both the outside of the bushes and the inside.

Get standard bushings and have a local machine shop drill the body and insert
the bushings or insert them yourself.

Subject: Re: [Healeys] SU carb reamer needed
With adequate resources it's clear that addressing both the shaft and bushing
would be the optimum solution. However as an impoverished student over 50 years
ago I recall changing out the throttle shafts on my Sprite, at minimal cost,
convincing myself that this made a difference! Joe Curto wants around $500 to
rebuild a pair of SUs. Now as a retiree I have more resources but still need to
manage how much money I spend on my hobby.
If the wear is limited, maybe shaft replacement only might be cost effective?

Might be a better idea to send out the bodies to someone like Joe Curto and
have them reamed and re-bushed for a standard shaft.

I have H6 carbs on my 100 Le Mans and the 5/16" throttle shafts are loose. I
would like to go ream out the bodies and go to the oversized .320" throttle
shafts. Moss wants $270.00 for the reaming tool and I do not anticipate I will
need to do this job again during my lifetime. Does anyone have one of these
they would be willing to loan or rent?
