Rallye Dash Resto

That resto cluster looks good, I can't wait to get mine. Another quick question, when I removed my bezel/cluster I noticed that I had every type of screw in the book, self-tapping, wood screws, cheese-head screws, etc. Would one of you be able to tell me what are the proper screws to affix the cluster to the dash frame and where to source them?

Thanks for yor help.
