I have a clear pickguard made for a 335 ... should fit a Dot ... I bought it for my Dot, but I decided that I'm going to sell the Dot, so I never put the guard on.
I recommend this pickups ... they will make your Epi Custom sing ... I own several sets of these ... they are well made and high quality ... superb bang for the buck ...
