Lets do a little comparison here.
Weld from a Denver area Toyota "shop" that claims to fabricate and build crawlers:
Welds from Addicted Offroad after they fully ground out all of the hack job work:
I can't say enough good things about Scotty and his team over there. All of the plates are fully welded, consistent, and defect-free. There is such a difference between a real fab shop / welder and someone who claims that they can weld.
Here is the slider that was rubbing as well. The local "shop" mounted it about an inch too far forward and it contacted the slider at full stuff. It really baffles me that the guy didn't even bother to measure.
To fix this, the guys at Addicted cut the slider off, fully ground down and fixed the old welds, ground the plates smooth, added even more mounting plate for the new location, sleeved the slider, and fully welded the sleeve and remounted the slider to the plate. This was a crazy amount of work just because I wanted to save myself the drive and save a few buck having that local "shop" do them.
Needless to say, but I sure won't be making that mistake again.
