Replacing hook guide problems

A home owner from Pennsylvania says:

The original installation by the builder in 2005 was a botched job. I have new guides to install but the spacers do not exist and the holes are stripped and they used 4 different size screws two with shoulders and two larger screws. What should I do? Cut the old guides to make a spacer? (will that be too thick). Should I drill new holes close by and plug the old ones? (With what) Any ideas.

Can you show pictures of the hardware in question? That would give us a better idea of what you're working with. Many thanks.

I installed the new hook guides but the holes are stripped and the directions say that I should use the existing spacers but the builder never put in spacers. Maybe that's why the food has never operated smoothly. Can I cut the hooks off of the old guides and use the flat part remaining as spacers then move the new ones sideways about 1/2 inch and drill new holes to use the new screws that came with the new guides?

Thanks for the picture. This reminds me of our 10-139 Shower Door Guide. We've had some past customers able to use a pair of washers in place of the spacers. See if that could work for you. You can read about removing and replacing these guides here.
