I know I have seen this information on this forum in the past, but I can't seem to find it now.
I need a new top-lever screw ~ one that actually matches the original, not the one sold by Numrich. Can someone point me in the right direction? Thanks for your help.

I don't have your answer, but if you use the search function on this message board you might find some help. Just type "top lever screw" in the search box at the top of the page, and a number of questions and comments will be reflected. Hope this helps.

Bert, your question is a little confusing, you stated "not the one from Numrich, one that actually matches the original." First you didn't state what grade you have. And how does the one from Numrich not match the original?
