If I could find some A1's I would be happy, but right now I do not have any. So there for they are not on my modification list.

I know Marco had a few sets awhile back, maybe I should get in touch with him again and see if he received and still has a set in stock.

He's got six sets as of last week, probably down to one or two by now.
