Found one in nearly new condition a couple years ago. Here it is on my 1650. Have several 42 inch blades, but only one 54.

I have a 42" on my 782, and I took a junk blade i had and cut two 9" wings off either side to bolt on the my 42" to make it a 60" things a beast, when i put the wings back on ill get a pic, made them bolt on so they can be taken off and wont ruin the plow.

I had a 54 at one point. Sold it with my 1650 man I wish I wouldnt have gotten rid of it. I never did get the luxury of lifting it with a manual lift tho
