3/4 ton/one ton brake booster brackets

[StingRay]

I have a 69 one ton. The PO scabbed a booster and master cylinder off of a late 70's disc brake truck onto it and the valving is incorrect and causing the brakes to be really flakey. I have a correct booster and bought a new correct master cylinder for it. I was wondering what if any kind of brackets are used on the heavier truck to brace the assembly when it's installed. I have half ton stuff but the booster for the heavier trucks is dual diaphragm and dimensionally very different. If anybody can give me any info or better yet pics of the 3/4-one ton stuff I'd appreciate it.

I'm hoping to upgrade it to disc some day but for now I want the truck safe and reliable with the stock stuff all working up to spec.
