Do I need to fill these?
 

Plugging along on my C30 and I’m getting ready to put the rear window in. This was originally a motor home and had a small pass through, I think these were part of that. Any reason I need to fill these small holes, maybe 20 (didn’t count). I’m hoping to avoid having to mess with them

If all the holes are close to the inner lip like your photo, I'd leave them as is. Keep in mind that these old truck windows and seals were not perfect to begin with and some silicone might be needed around the outer perimeter of the seal, holes or no holes. MY rear window with slider did not need any silicone, but the front one got plenty after the third attempt to seal it up by the glass shop. If the holes give you any trouble, it will the be ones along the top, but I really doubt they do.

I think Ill put a little dab of sealer on each hole and let it dry before installing window. Im hoping that will do the trick, like you said though probably not needed. Didn't want to weld them all even though they are very tiny.

Thanks for your input s472 =)

They were from screw in snaps. They must have had a snap in cover over the rear window on the inside for privacy. My Custom Camper still has those snaps.
