Aluminum is a soft material, I rather NOT press studs in cause its unsafe a company such as H&R uses a mixed aluminum for extra strength which is an expensive piece of material but much stronger which will support studs.
I suggest longer studs and you’re done, simple replacement and pretty cheap studs.
with a stud replacement you’re looking at a max spacer of 25mm possibly 30mm.
…… I can make you that style spacer but not aluminum, sure it might be heavier, but I can lighten it up with extra holes. Though there will be a difference, it wont be that huge
