Find and Place Formula

[campgrounds360]

Hello,
I am struggling to figure out a Find and replace formula for the following parameters:
Formula to run in entire spreadsheet
Find: "id": "0-site-151-interior" and "target": "14-site-151-parking"
I am targeting the numbers I have highlighted in red to replace with a different number throughout the entire spreadsheet.
Replace: "id": "76-site-151-interior" and "target": "90-site-151-parking"
I would like to add a specific value to each number shown in red. This example I want to add 76 to the numbers shown in red on these examples.

Any help would be greatly appreciated

Something like

=REPLACE(A2,FIND(": ",A2)+3,FIND("-",A2)-(FIND(": ",A2)+3),MID(A2,FIND(": ",A2)+3,FIND("-",A2)-(FIND(": ",A2)+3))+74)

Something like

=REPLACE(A2,FIND(": ",A2)+3,FIND("-",A2)-(FIND(": ",A2)+3),MID(A2,FIND(": ",A2)+3,FIND("-",A2)-(FIND(": ",A2)+3))+74)

This worked beautifully!!!
Thank you
