I have a 2001 3/4-ton Suburban and a Fisher Homesteader plow, that I had on multiple Jeeps over the years. I'd like to buy the frame mount and move the plow to the 'Burb but I need to know if the front-end mount points are different on the 1/2 vs the 3/4. Fisher in their infinite wisdom only lists heavier plow's mounts for the 3/4 and I don't know if that's because the two front-ends are different, or if it's just because they don't want me to put a light HS plow on a heavy vehicle. I'm plowing my same driveway with the plow, I'd just like to move it over to the 'Burb for the winter.
Thanks in advance!
I did do some searches but couldn't find the specific answer to my question...thanks again!
