hi Kim
just got a few comments from Andrew ( one of my techs) on the MB playfield
we have fitted one new MB playfield so far
Andrew found NO problems with the T nuts
some holes for the post weren't as deep as needed and had to be drilled a small bit
but rather this than be too long and have to re fill so no big deal at all
overall a good and easy playfield to install
and plays like a dream
very happy with it
thanks
mark
