Nice! Goes together rather easy. the grease on the screws is a great tip!
Tell you one thing if the diff balls are the same size as my 501x diff balls then
I have carbide balls already.
I have 10 new carbide diff balls in the package. So if it uses 12 then I dunno...
I dont think you can mix and match different diff balls as that would cause problems...
Now that I think about it those diff balls are smaller, so they wouldnt work..nm
