Tad out of season, Snow plow on 67-72?

[TP from Cntl PA]

I'll have my '72 K-20 pretty much buttoned up before the snow flys........I bought it for the intention of plowing snow in the winter, along with getting in and out of auctions during the muddy times of the year. I was curious if any of you guys had suspension or other breakage issues with a plow hung on the truck. I was concerned about the steering box mounting area breaking so I did re-inforce that area, but anywhere else? Since we do alot of open areas along with driveways I'll probably put a Western V-plow on it. We never had any problems with the older straight blade Westerns on our Ferds suspension wise, but I imagine the V is a bit heavier. I may need more helper springs in the front that I planned. Yeah I know, I'll probably wish I'd have put an auto in it, but for the few times I plow snow it isn't worth it..............Rather have the stick the rest of the year.
