Sliding window catch removal help?

Hi guys.

Pretty much as per title. 1 of my sliding window catches is lose and I'd like to secure it properly.
It sort of rotates in the glass and interferes with it's function a little.

Cheers

if it's a factory type window there's a vertical screw that holds the sliding part and the spring into the piece that bolts through the glass, access is from below it's not easy to do with the window in the van and depends obviously on the furniture in the vehicle

Awesome. Thank you.
I'll go have a look for it.
Any reason not to tiger seal the piece onto the glass if I can't just tighten it up?
Cheers

Found the pin and removed with ease. Thanks for the help. A screwdriver bit held in place with your finger and turned by a spanner made removel/fitment easy.
Found the problem once dismantled, only 1 screw in there instead of 2. Threads were done in the holes so I guess it's been bodged in the past. 2 slightly longer m5 bolts fitted and jobs done.
Thanks again Aidan.
