Hi Jon,
You did well to find it on the road!
A roadside repair is to knock it in with a thickness of rag all round. It'll probably leak or weep still but may hold water well enough to get you home.
If the hole is worn oversize, oversize plugs are available in 1/32" increments I believe. The perfectionists would have you machining the hole out to suit but carefully filing down the OD and repeatedly trying it in the cleaned up hole, especially if it isn't round anymore, should get you a close fitting plug. I always use Araldite on plugs mainly to corrosion protect the inner face but it does help seal a raggy edge too with a fillet run round the top of the plug. I have seen the edge of the hole popped over with a centre punch to help the retention. The king pin core plugs are more difficult with the pressure from a grease gun.
I hope that helps.
Dave
