You can still bend an idler arm with a gusset, I bent one w/the Downey gusset, and wore out another at the pivot. The best thing I have found is to buy a Moog idler arm w/a lifetime warranty, if they still come with one. I haven't had to pay for a new idler arm in 13yrs, but I have exchanged 3 of them during that time, 2 on my '90 w/33's and one on my '91 w/35's.
Rim width and back spacing will also effect the overall tire you can run before needing to modify the wheel wells. On my '90 32x11.50 on 15x8's w/3.5 BS rubbed on the body seam, but buddy w/92 cleared the same tires w/stock Toyota rims(15x7 w/4" BS).
On my '91 I am running 35's on 15x10's w/2.5" BS.
To get them to clear I used a 2" BL and 1.5" BJ spacers, and beat the fire wall back to the body mount. I carry spares for everything, but haven't broke a CV even with an auto locker up front. The only thing I have broke was a tie-rod end, but the breakage wasn't caused from the tires, given its age and conditions under which it broke, I think it would have broke with 28" tires.
