Hi
I'm looking for PE drilled plates such as those (included in aftermarket sets) used to replicate US trucks muffler "perforated covers" (M35A2, M923....). Aber should be a good pick, but they have 2 references in their range : S17 and S18. Which one should I choose, taking the size of the holes into account (the pics I have are not clear enough)?
TIA
