The eleven Guild dreads I have owned thru the years had 5 different pin sizes (most 5 degree, but not all), and unless you are the original owner, you don't know whether or not your DV has been reamed out for different pins.
Bob Colosi can make pins for you based on measurements you provide (scroll down in
this link), or he can copy a pin that you send him. He does good work and has great customer service (I have installed several of his saddles in my Guilds, and had one custom set of pins made).
