Jumped around a bit this morning. -Finished riveting the rear baffling together at the job near the oil cooler. Had to reinstall the oil cooler -Bolted the rear baffling back into place -Drilled the left rear corner rivet holes to #30. I'll use cleco's for now incase I need to disassemble something - there are easy to get to at the end. -Turned my attention to the engine attach hardware. Need to verify torque and put in the cotter keys. I got the torqueing done and I want to double check AC23-13 on the proper cotter pin installation before I finish. -Moved to the oil filter install - my spacer (3/4") from Vans. Removed the 1/4-20 stud from the accessory case and started running a tap into the 4 holes per the instructions when I ran out of time. Merry Christmas to all!
