John,
Hello again.
Pictures are attached.
As noted, this one is off an 80" and may be slightly different to the Series 2/3 in how it attaches to the bulkhead.
Cheers,
Neil

Looks ok for a '66 S2A, although the body end bracket may be slightly different but a Blind man or woman would be glad to see it. That fixes to a centre vertical galvd. channel.
