The owner needs $ I see the value of the dana 60 , so getting the rest of the car and parts for a decent price, he's having health issues, so not gonna be a tightwad after all he's good people
I know you could fix this but all I see is a parts car. I say $1500 max as long as all of the Formula S stuff is still there (tach, sway bar etc...). Work him down to the lowest he'll go and buy it.
