Hello trying to select a guide for these old windows. I have 10- 13 windows to rebuild. My guess is with the a little modification the guide 18-161 is the one I order.. (my spec see pics) 5/8, 3/8, 1 3/8, 1 3/4. Can you help me verify before I order. I have already failed at ordering and try on a different guide.. Thanks Scott

Hi, Scott.

I agree, it looks like you have our 18-161. Could you double check your measurements for us? There's a possibility your tape measurer might not be lined up enough. However, our 18-161 is still our best option for a replacement. Look it over and see what you think.
