Hey AJ that's what I ended up doing........my frustration though was that with the Buddy you can't get to the top bolts of the spindle mounting plate without having to remove the deck so as to lower the spindle down enough......
So to do trial error as you say means that I cannot tighten hard the top bolts because I ain't removing the deck each time I want to make an adjustment (especially 4 x 4 one).
Anyhow did the adjustment tightened the bottom 4 bolts and now no ridges I can hook my nails.
Oh the only other nuisance was that I had to oversize the bolt holes to get enough adjustment.....you think SB would have picked that up in the factory....obviously they don't plumb the Z accurately in the factory.

Hope you are enjoying better weather with Summer coming......it's **** here.....first snow in the mountains already!
