Rebuilding '92 Premier LX and NEED PARTS & parts sources!

Hi:
I'm restoring this Premier LX and need sources for new, rebuilt, or remanufactured parts which the dealers no longer carry. Just now I'm looking for body-side door weatherstripping for each of the sedan's four doors, particularly the driver's door. Dealer item number for this door's weatherstripping is CHR 04584409. Also need black underhood insulation, dealer item number CHR 35013402.
VIN #2E3CB56U4NH104597.

Any leads would be appreciated.

Thanks,
Steve <sguybh@comcast.net>
