I was eyeing those Ebay weights, don't know if they are the same ones you used? Set of 4.
I haven't removed my FEL yet, but if I did, I would definately need a front weight set-up. Also figured they could do double duty on a 3PH rig, too.
Not only are the Kubota weights a little pricey as you mentioned, how bout that factory bracket? Ouch!
Again, Nice job, very nice indeed.
