This is an original Harrison 3157804 Heavy Duty Oil Cooler Assembly. This was recently removed from a 1969 Corvette that was being restored to stock condition. These were used on many Trans Am and other road race applications.
I have put this oil cooler up for auction starting at $9.99 with NO RESERVE. The high bidder at auction end will be the new owner.
If you would like to check it out, here is a link to the auction:

I would like to offer free shipping to paid members of this site in the Continental US and $30 off shipping anywhere else in the world. If you are a paid member and win the auction, please send me a PM and I will send a corrected invoice through eBay.
Thanks for the ad and happy bidding,
Jason
