Just found the measures I provided to customwires ( firecore ), measured per customwires specs, from center of terminal to center of terminal. Measured the NOS set I got to get the firecore set correctly done

Coil---9"
1-----22 1/4"----90º boot ( cilinder 2 )
2-----25----90º boot ( cilinder 4 )
3-----31 1/4"----90º boot ( cilinder 6 )
4-----40 1/2"----135º boot ( cilinder 8 )
5-----43 3/4" ---- 90º boot ( cilinder 1 )
6-----48" 1/2" ---- 90º boot ( cilinder 3 )
7-----55 3/4"----90º boot ( cilinder 5 )
8-----56 1/2"----135º boot ( cilinder 7 )

This is to use the stock wire brackets ( which need to be trimmed a bit to accept 8 mm wires )
