knobs broken off - only one working

Although my gas range is older, it is still in excellent condition and good working order, except for the knobs. I was down to one know which I moved around for all the burners. Found your site, instantly identified parts from your pictues & diagrams. Rec'd new knobs. Slid into position and away I went. It is like having a new stove. Knobs were a little pricey - but well worth it.
