Great DIY and great help. Here's the deal: I have 2 e90s and changing out the entire leatherette with leather from the other car. ie...one is premium package and the other is not. So, technically I have all the parts needed including hardware. To clarify, the donor car has folding split seats the "new" car does not. The only parts I'm thinking I might need to purchase are the plastic screw holders that expand when mounting the manual seatback release handles..... Thoughts???? Am I missing anything here?
