Very nice GN! So, your car was purchased from California? I spoke to Shaun M. a few days back, and he mentioned you had attended the NAPA show, recently.
I've asked Shaun to pass on to other GNRA members the details of the upcoming All GM Picnic on July 5th at Campbell Valley Regional Park inLangley. You can see my thread, regarding the show, within the forum. Would you be interested in coming? I, and many others, would love to see your '87 GN at the show.
