M Door Sill E46 330CI
Hey guys, I have an E46 330CI and I'm trying to replace the door sills and replace it with the M door sill.
1) Anyone know where to get a reasonably priced one? The dealer is charging $178 per side.
2) Is there a proper way of installing it?
3) How many clips do I need? Should I be aware of breaking the clips?
Thanks for your help.
