so, i have always thought that when toyota changed to ifs in 86 that they changed the gear size to 7.5 for ifs front and 8 in the rear. am i not right??? i just sold my 4.10's from my 89 to a guy with an 87 pickup and he said they looked smaller then his old gears. he said he put his rears in the front???? but an 8" couldnt fit in a 7.5 could it??? am i just missing something or what.

solid front axle uses the same 3rd & gears as the rear
