Carefully measured, positioned, checked and pilot drilled the parts to the firewall - following the construction guide and the Plans measurements. Completed the front and the back (not shown in pic's). Then I checked all the measurements again. checked for square and level and drilled the pilot holes out to the correct size. Very time consuming but very, very rewarding. Now it's disassemble, debur, prime and rivet. Tomorrow
