will a lift kit for a 85-89 4runner fit on my 90 yota 4x4 truck?

 

85 is leaf sprung in the front, but 86-95.5 front is all the same IFS.
Rear is different tho depending on the year, pickup has leafs for all years, 4runner has leafs in the rear from 84-89, then 90-95 is coils.

So the front will fit, rear will not depending on what year the lift kit is made for.
