I own a 1976 Chevy K10 which has a total of 4 leafs on the front end. I'm going to be installing an older 8 foot Fisher plow that I purchased for $625 complete. The truck it came off of had 4 leafs on each side. I've seen many trucks of my vintage that have 3 on each side. What do you guys recommend? Leaf shop has a pair of 4 leafs for $260. JcWhitney has a pair of 3 leafs for $170.
