plowing along....
I've had several GM 4x4's for plowing since 1987...only the last 2 trucks I had were K20's..ALL of them had the 10 bolt front ends,or a dana 44 axle,and stock leafs up front..a few of them,including my 82 K20 with a 6.2,only have 2 leafs in the front springs!..
I had an 8' Fisher plow on my other trucks that was a real heavy S.O.B..about 450-500 lbs!..I never broke any springs or axle housings,or even axle shafts...in fact,I never had any trouble other than a few outer U-joints going bad due to rust!--and front driveshafts CV joints going bad,or a hub or two give me a bit of greif......
I wouldn't say the 10 bolts are "weak",sure,they WILL break easier than a Dana 60..but I've yet to own one,and don't feel its really nessasary..nice to have,but not a "must"..I didn't beat the living snot out of my trucks or get them airborne(much

) either though..I did have to whale on them a few times when we got over 2' of heavy wet snow though,and I never plowed until the storm was over..
I'd prefer to have a K5 for plowing driveways..they are every bit as rugged as a K10 or 20 pickup,and the short wheelbase is better for manuverability in tight places..I'd say an 8' plow is a bit too big for one though,(but I see many pushing one here!)...I'd say a 7.5' is perfect..
I'm not that familiar with a Western plow frame,but its probably similar to the Fisher I had if yours is hydraulic..mine had 2 plates that bolted to the outside of the frame rails,and a "C" channel that bolted to both of those plates like a crossmember,where the plow's "A" frame pins would hook on..and another frame bolts to the plates in front of the grile,and holds the piston up,so the plow can be lifted..I'd search on E-bay or Craigslist,there are several pictures of plows and plow frames for sale there..at least on the "boston" craigslist there is..
