Hardest thing to sell is mechanical parts and such an be a can or worms. I had a bud that did well with such but he was a lifelong mechanic/engine tran builder. Buy mechanical parts YOU want and check them out and hold it.
Also, it takes special buyer to step inup and buy such a large lot.
True, such deals comealong seldom out in the sticks. You aren't in N.J. ToeDoe!
There are Moparguys that can buy such and set it in their shop and get all fuzzy eyed just looking at it all!
