The 6.2L and 6.5L are very similar, and the external parts such as injection pumps will swap between them. The 6.2L injection pumps are calibrated for less fuel delivery than the 6.5L, but the difference isn't that great.
Lots of places to purchase mechanical systems. For new, start by checking with some of The Diesel Page supporters:

You will also find lots of used items on eBay, etc. Just beware when purchasing used, as you can't tell what condition the pump will be in. Factor in the cost of having the pump remanufactured just to be safe.
