My friend,Billy W.,installed one of those dual-reservoir/booster units,on his '59 Viking. It DOES NOT WORK!! Some vendors will tell you anything to sell their product,but hesitate to back their claims. With the drums adjusted,the left front and rear grab,while the right wheels spin freely. The bore is 1-1/8,when it should be 1-1/2. Please do yourself a favor,and find a later model 2-ton set-up,with the correct bore/2 hydrovacs. This will save you a bunch of headache,as well as hours of wasted time. Just my 2 cents.
