I have an early model year '03 5500 and I'm wondering if I get the extended warranty on the injectors like the earlier model years do. I bought the truck in April '04 after it sat on the dealers lot since October '03. Will the VIN help in answering this question? Thanks for any help...

dunno if the med duty is covered for sure and I know that the 03's are dealt with on a case by case basis.
