I've found that most of my money hasn't gone into the '97 conversion, but upgraded parts like the lift, wheels/tires, the 4wd conversion and maintenance items like new brake components, battery, etc. So, if the conversion was done well and the maintenance has been performed, then I can see $4,500 as a fair price (I know I've got way more than that tied up in mine). I'd pay that if I were looking to get another one. All the little stuff adds up. If the cluster came from the same donor as the motor, then that should give you an idea how many miles are at least on it. When people ask me how many miles are on my truck, I have to ask them which part?
We still need to see pictures.
