I'VE GOT AN EARLY 1999 FORD POWER-STROKE 7.3L WITH BRAND NEW INJECTORS IN IT. JUST WRECKED THE TRUCK AND BOUGHT A 2003 7.3L THAT NEEDS INJECTORS. CAN I SWAP THE INJECTORS FROM THE EARLY 99' TO THE 03' WITH NO ISSUES OR CAUSE ANY HARM TO THE ENGINE?

No problems at all - both are split shot injectors UNLESS the person who put the injectors in the 99 ordered single shots in which case you'll have to reprogram the PCM to drive them. Do you know where they injectors for the 99 came from?

I believe that the early 99s don't deliver as much fuel as the later 7.3s do. The early 99 has 130cc (AB code) injectors and the late 99-03 has 140cc (AD code) injectors.
