If you can post that old info I'd sure like to see it (or a link to it). I just measured the spring pockets on my 5.2 OE mags & they are narrow (I left the sheet in the garage) but the dia is way less than 1.5" which I believe I read is a good move to "open the pockets up to use common 1.5" springs" & the parenthesis quote was what I read regarding this which is why I went & measured mine yesterday. I'll grab (& post) the note tomorrow.
