Looking good GTN great find!!! 
Yeah about that. I already busted a bolt off, I'll have to be a bit more careful! I gotta free up the turning part, as it took hitting a brick building to get it straight! Not something I want to do all the time.Sweet Blade! a word of advice,if you are going to adjust the shoes,soak the nuts with some rust penetrant or use a torch to heat the nuts -those are welded studs that love to break off and its not much fun trying to slide a bolt thru to replace from behind it!! have fun in the sand box :thThumbsU Steve!!
