Shim 1"x1"
This patio door guide appears to be an exact match for the 86-025 Crown/Lawson Guide. Take a look over the dimensions below and compare them to your guide.
These can be purchased directly from the website.

the one you are referring to is too big… Look at the picture I sent and that is it in my hand… It's small
The 86-025 is the closest replacement match we have. Our 29/32" (0.90625") measurement shown in the diagram is smaller than the 1" measurement you've confirmed, the 1-1/16", is only 1/16" (0.0625) larger than 1". This should not affect the installation.
You'll also notice, like ours, yours has a v-shaped curve on the closed off end.
While I see the photo of the piece in your hand, unfortunately, the size of the piece cannot be measured using the photo. The best way to confirm that this would be a fit would be to compare the dimensions of the part.
I hope this helps.
