I have read a in a couple threads about people switching their leather seats for cloth seats and vice versa, but are all models interchangeable with each other? I have found two potential issues: I guess in the earlier models (91-93) the seat belt buckle was not integrated into the seat? I need clarification on this as I have a 97. Also, are cloth seats from say a 94 a direct fit for electric lexus seats? I really want to get away from the electric seats as many here have stated, but also they just ain't holdin' up the way I want them to.
