I have an 83 250 that I wanna take the cab and replace it with a newer 96 cab will it bolt right up or is the bolt pattern different? all I wanna change is the cab

 

I know it has been done in the past. I had a 88 f450 and we put a 96 cab on with no problem.

 

Ok well would any of the wiring be different is the 96 cab an obd2 or can I use the same diagnostics as what the trucks got

 

you would have to use the wiring out of your old cab. You would not be able to use much or any of the wiring on the 96

 

Would I be able to use that gauge cluster or would I have to change the dash?

 

You will not be able to use the cluster. What are you going to hook the cab harness to? I am sure your truck has a cable driven speedo and the 96 is electric.

 

Ok it's a 89 body what all modifications do I have to do it has the computer but I know that cluster is cable driven but I need all the gauges to work can I use a 89 harness do I stock with the old one what's the best way to go with this?
