The oem height was set to run 31's. On my '90, 32x11.50's on 15x8's with 3.5 BS only rubbed at full lock, or when entering a driveway at speed. After beating down the fire wall, there was no rubbing issue. If you were to keep with the 9.50 width, you likely wouldn't rub with 32's depending on the backspacing of the rims you have.

You might give the local Toyota yards a call and see what they have and how much.

When searching craigslist ads, look for V6 5spds or autos. The V6 equipped trucks and 4-Runners were the ones that came with taller gear. 4.56's gears were part of the 31" tire package for the 5-spd's early on, and later were on auto's with 30's depending. The door plate would have G25 on it for the 4.56 gear code, whereas yours with 4.10's should be G29. The 4th digit on the gear code is for the number of pinions the 3rd member has.
