89 Dak..what would you do??

Drive it.
I fixed an 88 and gave it to my daughter to drive.
I was given the truck because it had a miss in the motor. Burnt valve, fixed it the truck had 150,000 miles on it.
She drove it for about another 60,000 miles then the transmission went out. She sold the truck for $900.
Those 3.9 autos are really dependable trucks.
