Thanks to all who commented, both on this forum and privately, on this
subject. My objective in using the wider shoes was to reduce brake fade
under emergency stop conditions on steep mountain grades Theory
notwithstanding, actual experience by those who have installed wider shoes
is that there is no discernable improvement under those conditions(except
for this situation, the OEM brakes are adequate for the way I operate the
vehicle).
On to a disk brake retrofit, at least on the leading rear wheels... 'Knew
that would work but installing wider shoes was a more expedient solution.
As Packard enthusiast Dave Greenberg remembers, the old Packard Motor Car
Company promoted the sale of Packards with "Ask the man who owns one".
'Could be modified for GMCMh owners to "Ask the man who has done that".

Fred,
By going with a drum in the rear back , your defeating the full
advantage of the disc. system.
I have been working with few people in perfecting the caliper parking
unit like the one on the Eldorado rear disc. system. I know that if we
wen with all 4 rear parking calipers, it would work, but will not have
the full advantage of the 80mm.
The limiting factor in the rear parking caliper is the lack of enough
force needed to lock the pads.
We have been using Albert Branscom's cable system, but that is another
$500 that we do not want to involve.
We are going to look at a foot operated system as we need more force.
I'm going to have Chuck Augur work on it to see .
