On my 56 292, I have the reproduced wire brackets.
I have installed all the wires, except the last one
which goes to the block in back next to a bracket that
has something to do with the throttle linkage. This
bracket is opposite the distributor. I think
that last bracket is secured to a bolt that also holds
that throttle linkage bracket.
I've looked thru all the pictures that many posted,
incuding those from Ted, but cannot determine which
bolt hole is used.
I spoke at length to Miker and we tried to figure out
which hole is correct, but I don't think his T-Bird has 
that passenger bracket.
I just want to be sure I secure that last bracket correctly.
Any comments/suggestions appreciated
Jim
