Any one know where I can get a screw for a slide plate spring for my 185J? I went to put it on today so I could securely attach my slide plate and found out the head was ripped right off. Which was probably why the slide plate and slide plate spring were missing in the first place. I got the slide plate and spring from Sew-Classic - I sent an email about a spring but I have a feeling it's not going to be something in stock.
