HUB adaptor. 5x120 - 5.114.3

[P3Z]

ive come across a heap of wheels meeting my needs and price range, but theyre all seem to be the wrong size.
my e36 runs 5x120 and all i have found is 5x114.3

i know there are hub adaptors, but id rather not spend $300 on them IF there is an alternative option.
can i have them drill them out and get the holes threaded or is this not a safe idea?
or is there a better way again?

Drilling is definitely an option but I am not sure I'd do it myself haha.
