My friend has a V10 conversion truck. There is alot involved to switching over like front springs, dash, cruise control switches in steering wheel if he wants the cruise to work properly & by dash I mean complete harness & dash, odometer cluster, modules. The engine harness, brackets, crossmembers, PCM, ECM..... everything. If he wants a Cummins..... this guy builds them all the time switching wrecked v10 trucks into CTD trucks & he really has the answers. Jim Balsley 724-455-6100. Give him a call... . he will do the conversion or atleast explain it in detail. He also trades for CTD trucks... . anything Dodge.
