the non PS rack has what you describe on it, studs
sleeves are the easiest way i think, i will need to fit the PS racks front and back plates on to cover the larger sized bushes on the arms with the adjusters.
It wont be for a while though, still have a bit to do...
fit the race springs,
get filters and mounting plates made to fit on the TB's,
spec an oil cooler and fit it,
get the clonking adjustable panhard rod sorted,
re-install all the interior,
re-wire and re-fit the ICE to be made easily removable for track days,
get light bucket seats
Fit the 1.3 sud gearbox.
and possibly a roll cage.
Might be finished mid next year, just in time for Alfa day..
