Upright machining?

He's talking about the astra ball joint I think and not the complete hub.geometry would be totally different with GM parts.

Anyone got a link to this reamer?

I did mean the astra bottom ball joint, it has the same taper as the sierra.

Take care though, easy to over do it.

And the taper is correct on those?

Which one is correct the 19mm or 12mm??

Silly me. You'll need the 19mm reamer as the taper is 14-16mm if I remember correctly.

1992 - 1995 Cavalier has exact same taper/pin dimensions to the one in the Sierra TCA. I used it on a previous project years ago though it would require a slight redesign of the lower wishbone.

As for hand reaming the taper I'm guessing the hand reamer has the same 14°taper as the ball joint but how can the hand reamer be accurately controlled to prevent it 'wobbling' as you ream? I didn't think this type of tool was for reaming such a deep hole with required level of accuracy.
I thought it was for de-burring holes and providing 'lead' in to holes
