Mansker,
They look real good and a nice advantage is that you can use them without having to take your toothbar off. With my clamp on forks, I have to take the toothbar off, and while that is a simple job, it still is a job to be done twice(once off, then back on) when I want to use my forks.
I may build a set similar to yours at some point in the future...along with a light duty grapple...and...and... /forums/images/graemlins/grin.gif
Thanks for posting the pictures!
