[HWYSTR455]

I dug a little and got side tracked, but have seen others using between .025-.065, which makes me wonder what the sizes H-O kit used.

There are many that offer the plugs pre-drilled, many don't list the size for the front one, but the rear one I've seen many .040 sized.

I have a bunch of the H-O ones, and some I pulled from cores, but haven't measured them yet. Was also trying to dig up my H-O catalog from the day, but haven't tried too hard looking for it.
