E28, did you used to live in NorCal and have a brother who was parting out a 318ic? I used to have an E28 and think we may have traded posts on BFC.
If you are going to reupholster the panels, I have a pair from a 95 sport ti in good structural shape except someone cut out the speakers and left a speaker sized square hole. You are welcome to them if they help out. They are clipless as I needed them for the replacement panels I ended up finding.
PM me if you are interested. Cheers!
