Here's a couple of fresh pictures of the strap.
The important numbers are:
- Material - hard copper.
- Strap - 3 3/8 in L, 5/16 in W, 0.018 in T.
- Holes - 3 in ctr-ctr, 0.300 x 0.150 in, round ends 0.075 in R.
- Insulation - 2 1/2 in L, 0.025 in Wall T.
Hole centers are approximate. If I was to reproduce this, I would use a thicker material, 0.025 in max, maybe soft copper, and use shrink tubing but shrunk in the middle only.
If you note the picture of the strap by itself, it may have been installed loosely at one end as it shows signs of arcing and the insulation is melted. It was part of the modified C5GF-12127-A distributor I got from e-bay.
