Fiji Cube 48 Stand Setup - Need Help with missing parts

[RobCamer]

My wife and I purchased the Fiji Cube 48 (Build thread coming soon) about a year ago. We finally were able to find a house and have an offer accepted. We've been renovating for almost a year. We are at a place where we can setup the tank and get cycling. We opened the stand box and it was full stop. One of the back pieces is missing the plastic insets that the bolts are screwed into. Pics below.

Is this something we can quickly get at Home Depot? Any suggestions? I did reach out to fijicube but we are hoping to get unblocked sooner if it's a standard part.

What the board should look like with the plastic insets in the holes.

You can possibly get those inserts at lowes or home depot. Both stores have some shelving/entertainment stand parts in the section with screw bins.

Edit:
bring the screw with you to mach threads. You may end up with brass inserts.

Thanks for the suggestion. FijiCube got back to me and are supposed to send me a set of inserts.
