If you decide to buy the 2003 Gillig pieces, I would strongly suggest buying the Cummins Insite/Inline tool. Mine is the Inline 5 which only works on 32 bit XP system, but I have a dedicated laptop for it. Check out http://rawze.com/forums/index.php, great site for tuning your motor. You'll also see links on getting the Chinese copies of Insite to work. Another good source is the Cummins website. Enter your serial number and it'll let you know all the components in your motor. https://quickserve.cummins.com/info/index.html
Another thing that I did, the Cummins quick serve was able to tell me the ECM programming for my 280 hp transit bus. I searched RV ads for coaches that had Cummins ISM motors and found a comparable coach that was rated for 450 hp that had the motor serial number. I added that to quick serve and was able to get the ECM programming information. I also bought the rebuild hardware for the 450 hp motor when I had the motor rebuilt. Head, pistons, and injectors were all different. Cost between $8 and $9k for all the new parts.
