Anybody have an extra one of these they would be willing to sell? I am needing one now, and I have talked to the store on ebay, and they said they will have another shipment here in a week or to, I just can't wait for it. If anyone would be willing to sell one, I will pay a little extra for it to cover your time. It must be NIB though, hopefully someone can help me out. Thanks!

Mine has been on for almost 300 miles and is working good. Non vented type for me.

It is an AC-Delco. I bought one some time ago, and used the opti portion with an MSD cap/rotor. Has worked flawlessly.

Well.. something must be different. Why is the cap a different color and why does the drive pin not come out like in my old ac delco? They may be using some ac delco parts, however, these are not the exact pieces that you would receive direct from a GM dealership.

I got about 500 miles out of mine

now my engine shuts off intermittently and wont fire until it cools off a bit. The seller told me if I send it back he'll replace it.

I have one on my Vette, with no problems so far. About 300 miles on it.

So i removed mine to send it back and while i had it out i turned the drive pin and i can hear scraping inside on each revolution. Probably screwing up the optical sensor. ah well. i ordered an OEM gm replacement from a dealer.
