Default Flex fuel injectors?????

I got a 2003 5.3L engine, LM7, regular injectors. I got a 2005 wiring harness and computer from a L59, flex fuel engine.

Can I just change the injectors in my engine to L59 and everything will be OK?

Any reason to not do this? Is it easier/harder to program regular injectors vs flex fuel injectors?

Any problem with running a 2005 PCM on a 2003 engine?

Still trying to get above the learning curve on my engine swap.

Default

Also, will a flex fuel injector fit in the same fuel rail/intake as a non flex fuel injector?
