Sparky, a few years back it was really bad and we lost a lot in earnings.
This was a long weekend here so I did manage to get quite a bit done on the car.
This radiator box is a never ending saga.
I keep finding more to do.
I needed a good way to attach the lid and at first I was going to bond and rivet angle brackets (14) to the inside wall.
That entailed a bunch of rivets, rivnuts and getting every one of them lined up exactly.
I was looking at the Aluminum rivnuts and they have a built in washer with raised areas all round the circumference for grip (I guess).
It came to me that if I inverted the rivnuts and bonded them into the walls of the box they'd be perfectly anchored.
I marked the lid carefully, drilled 14 x 1/4" holes through it and placed it accurately on the box. Then I taped it in position and drilled all the pilot holes.
