Just remembered about this. Our setup on the 410E is slightly different than yours and looks to be aftermarket.
That looks close. Hey. Could you get me the dimensions between hooks at top? Dimensions between pin holes at bottom. And what are pin hole sizes at bottom?
I just remembered when I bought my grapple that the sales rep told me they will sell the mounts separate if I ever wanted some to weld on other attachments I may have. May be an option if you can find some cheap forks on CL or an auction.
37 1/2" inside edges of the plates at the hooks and at the pin holes at the bottom. Hook plates about 1" thick. 2 3/4" hook opening. 1 7/8" pin holes.
As far as cordless grease guns, best I have found so are the Milwaukee units. Last the longest and warrenty is great.
Gotta agree on the Milwaukee grease gun. Bought the 18 volt gun only since I had an impact, charger, and a few batteries at home already. Much better than the Lincoln guns we have at the resort.
We're the Lincoln guns 12v or the 14.4v? Guys in the heavy equipment shop I worked in learned the hard (and expensive) way about the 12v guns.
