Bolt on uses a smaller stub so the upright has a smaller hole for it to fit into.
I know that but alas your message above with the measurements is ambiguous unless big upright means the same as big stub and small upright means the same as small stub.
Sorry to be so fussy, but there was talk elsewhere about different sized uprights for higher performance, viz Spitfire versus GT6 which has confused the issue. There seems to be four possible combinations not just two.
