55.2-59 3/4 ton front springs

[MJN]

So, I've asked this on a couple FB groups as well but I'm looking to get new spring packs made for my '56 3600 Napco. The GM Data book/info packet shows 3/4 tons (3600) got front spring packs with 6 leaves- the master parts catalog also confirms this. My truck has 8 leaves- no idea if when it was converted to a Napco heavier springs were installed. They look factory and have the double wrap at the rear pivot and the spring clips in the factory locations. It did have a heavy snow plow on it prior to me buying it. 8 leaf spring packs, according to the parts catalog and data book, were for Forward Control chassis and 4000 and heavier trucks. Does anyone have a 3/4 ton pickup with 8 leaf front spring packs?

My rear packs have 9 leaves and match what the book says- besides the lift block added for the Napco conversion.
