Looking to buy MSD spark plug wires

[d0n_3d]

Where can I order these plugs online? I want the MSD 8.5 mm for the 87 GN in red...I think summit sells these but what is the part number for it? I can't find anywhere else that sells them online...not even the MSD website has an order page

According to MSD website, the part number is 31869. If you're on Summits website, the part number is MSD-31869.
