SR3500 upgrade

[bear]

Also received my 3500 upgrade.
Found 2 things not right , First the rivet drawing
for the skin doubler is not readable and secong I
believe I need 5/32 tank rivets for the rear spar
doubler instead of the rivets I received. Other
than that I have almost completed the rear spar
mods and the front spar mods for one wing.

This week I tried to reinstall the sill after modifying the landing gear box. It turns out that the new steel flange plates that bolt to carry through 2 and 3 have moved out causing the sill not to wrap around to match the old holes. The holes at the top of the sill are 1/8" from the holes in the side skin, this is only at carry through 2 & 3. Has this happened to anyone else? The steel flange plates have pre-punched holes that match the carry through. I'm thinking that since the old tabs on the carry through could bend each builder could have slight variations when wrapping the sill. If the steel flanges were not punched at the factory they could be installed to the sill and backed drilled insuring a fit. This is what I'm thinking for the other side. Does anyone see a problem with doing this? Does anyone see another solution? Replacing the installed steel plates at this time is not an option that I want to consider. There are 12 or 13 bolts in the plates, drilled and reamed. I don't think those holes can be redrilled and not go up one more size also the landing gear support and strut attach parts may not go oversize either. The belly wrap will cover the missed matched holes and adding a doubler behind the door post skin will fix part of the problem. The last part of the solution is replacing the corner wrap from carry through 2 to the firewall since that does not align either.
