What Series of EXP II with Lug Holes?

[Lubrifar]

Happy New Year All!

As the title reads, in terms of series, from when to when did the EXP II came with lug holes on case?

I read some searched posts that SEL only comes equiped with non-lug case; is it possible to find a series with lug holes and SEL EXP II?

Last question, are there any difference in packaging and contents between newer and older EXP II series?

Thanks y'all!
