Item description from the seller
Seller feedback (1,008)
- *****- Feedback left by buyer.Past 6 monthsVerified purchaseI found this harness for my Corvette and contacted the seller and they were very, very helpful and once purchased I had the item within 2 days. This is great. Now come the hard part for me is top remove the old harness and replace it with the new one. This was a great seller and the harness is brand new in a sealed bag.

I gave 3 stars cause everything bolted up perfectly but I ended up needed new heads again due to these being so chipped up around where the gaskets go
