Hi,
I don't know who makes the "best", but I have the pair YOU should buy.
I think these are for a Skid Steer and are heavy, not bent and about 60", but I would have to check tomorrow, 060817 if you are interested.
I wanted to use them on my frontend loader and weld a fitting to attach. However, I am selling the forks, a Koyker 160 loader, a new flail mower, a never used posthole digger and some other various small 3-point attach as my tractor, a Lamborghini I bought new in 2005 needs clutch plates and I've decided to sell it, as such, I don't need the attachments.
Let me know as I will be listing all this stuff soon.
Good Luck Hunting
