The only part that I had to adjust was one of the top capstrips that must impinge on the main wing attach plate. multiple trips to sander until I got the fit I wanted. I had left that capstrip long for that purpose.
The rest was done with strings and rubber bands.
Capstrips matched drilled undersize w/ #40 . I then just used ad4 rivets as pins to hold rubber bands.
The web splice has to positioned to avoid rivet holes near spar edges. In the case of the patrol it is called out as 1 9/16. It is not a precision thing it is just what is required to get rivet to edge distances.
Also, the rivet spacing on the capstrips changes near the web splice. Some of the rivets are moved. Some are not

If at all possible do not predrill holes in capstrip near the web splice areas that have a change in rivet to rivet distance. You can mark the holes with do not drill. You can put tape over the holes to remind yourself not to dirll. Non of it matters when you start drilling your brain turns off and you drill every hole in sight.
The same thing happens when riveting. There are rivets to hold up fuel tanks and 4130 bars . You know that they are not supposed to be riveted. If you are like me you will rivet all of those locations and have to go back and drill them out. If your really as bad as me you will anvil the rivet -then drill it out - then put in another rivet and only latter realize there is not suppose to be a rivet in that location.
