There is a guy on ebay selling many items that he says are from an '87 - warning THEY ARE NOT. some may be, but be wary if you bid on any of the '87 stuff and make sure it will work on your car. One guy bid on something, and found out it won't work - he contacted the seller and the seller won't let him out of the bid. I've emailed the guy myself to let him know a particular item was from an '84, not an '87 and he now insists it's from an '86, which is obviously wrong (obvious to those of us that know more than the average Joe about Z's).
His ebay name is carpartsrus. I'm just saying that his parts may be good, but make sure if you bid on something that it's something interchangeable with the year model you have.

 

Thanx for advice!
