Hi,
I use the Amal spacers, they are 3/16" thick with different bores something like 28,30 and 32 mm comes to mind.

Best wishes...

I would recommend the thicker spacers the better as the thinner ones can distort and create air leaks. You may need to fit longer studs, depending on what has been used before.

Hi Roy,
None whatsoever. I would trust Amal to get the dimensions and material right, here's the link:
