Drew,

I think the Yashica-D and the Yashica-Mat have the same Copal shutter. I just finished repairing the shutter on a Yashica-Mat (mine) two days ago. I didn't find it easy, but it was challenging. I thoroughly reviewed the images located at http://davidrichert.com/yashica-mat.htm which help immensely. (click on images to make them bigger and read texts provided). Anyway, I don't want to advise wrong, but to get at the screws I had to remove all the leatherette material on the front face plate. If you do this, take your time as not to slip and scratch something. My leatherette material was petrified. A set of jeweler's type screwdrivers is a must. I also got my shutter to work, but the self-timer is wasted, which is perfectly fine for me. Best of luck to ya.

Sorry, if I barged in. There's simply no excuse for my behavior.
