The other idea would be to fabricate an adjuster that fits inside of the return springs(if there is room).If you run out of travel in the wheel cylinders then you would have to fabricate longer engagement pins.The original hold down pins could still be used.
NOTE: when you take the shoes off of the backing plates make sure the bearing surface for the shoes are flat(fill in any groves that are worn in the backing plate) The shoes need to run true to get proper adjustment.
Thanks for the info, I may have to check this out, it may come down to getting another rear for the truck, something more part friendly but thanks
