I've owned and refurbished a fair few Model Ms in my time, until now I was fortunate enough that they had enough of the rivets in place not to require bolt or screw modding. Unfortunately my most recent acquisition is missing a lot of rivets though (I counted 24 and some more are loose)
I've done a fair bit of research into bolt/screw modding and decided that the best route to take would be to screw mod it. The only problem is I can't find any information on what size screws to use, or what guide hole to
The closest I have come is
this thread that recommends 2-56 x 5/16 screws and a 0.070" diameter pilot hole.
Does any else have any recommendations for what to use or a rough conversion for the drill bit and screws above in metric?
