Small remaining task on the rear anchor blocks. I still had to drill for the screw that hold the UHMW plastic block in the aluminum enclosing.
Depending on the height of your rear frame pin entry point, you may want to play with different positions compared to the ones given on the plans.
Mine are still ok and I drilled in the plan locations. As I still have some priming to do, I secured them temporarily with anchor nuts.

Now that the anchor blocks are placed and all is locked in position, it's time to drill the remaining holes on the slider bar to full size.
I marked the positions as per the plans making sure they are in the middle of existing rivets.

After drilling, it looks good from the inside

Here are the holes seen from the top.

Finally installed the screws and nuts and torqued them for permanent installation.
