consider using 69 hinges, they'll hold the hood open more than the 68. I'm changing my out this summer. Gene
The 69 hinges will work fine and you won't crack your skull every time you go under the hood. Use them.
Well, 69 hinges do bolt up to a 68 hood, I swapped 69's onto my 68 a couple years ago for the added headroom. If you're set on 68's, you can have my old set for the cost of shipping.
