The wings i saw were for 1/2 3/4 and mini trucks. the wings were only 4' i think they were made out west somwhere . was thinkin the price wasnt too bad on them somewhere around 2500 or 3000. i'm still lookin for the flyer they sent me.
Bolensdriver - Take a look at the sidewing. Their website is www.sidewing.net. You can also do a search on here for sidewing. There are a couple of guys on here that run them and they swear bye it and some of them are inpretty serious snowfall areas. I saw on at the fair a couple of years ago and they are quite rugged in construction and ingenious in design.
I paid around $4-500US I don't remember exactly Looked half-a$$ed in the pics, supposed to have some rust. Didn't mention that the 1/4" thick c-channel framework was completely rotted thru and buckling etc. Very little to work with. Needs a completely new frame and some major surgery to the hopper. Chain drive doesn't look so healthy either.
I WILL fix it, mainly because I refuse to take a total beating on this, but would have happily paid twice as much for a good one...
