I drilled the forward strut mounts to the canopy frame using a #21 bit. I was a little worried that the bit could damage the threads I already tapped into these holes but it was a non-issue. The shavings did clog up the threads, but running the tap back through them cleaned them up nicely and the screws still threaded in snugly.
I then clecoed the skin back on and opened the holes up to #12.
I attached the mounting blocks using some scrap bolts. The frame will eventually get countersunk and the skin dimpled, so these will be replaced with flush head screws, but this is fine for the remainder of the fitting.
Here’s the inside of the mounting block. The ball fitting for the strut will thread into the center hole.
