Injectors for 2003 5.7 HEMI

[mkbrower]

Hoping someone can help. I have a 2003 Hemi that needs new injectors. The Original ID color is green which seems to match the 4.7 engine. I have read and verified in the service manual that 2003 injectors are 48lbs while 2004-2008 are 60lbs injectors. Only injectors I find for the 5.7 are for 2004 up. If anyone could point me in the right direction I would really appreciate it.

Up through 2003 the fuel pump only put out 48psi, this was upped to 58psi in 2004.
2003 5.7 hemi injector - 53032142AC
2003 4.7 injector - 53032145AA
2004-08 5.7 hemi injector - 53032713AA

Actually thinking about the pump pressure being 48psi for the 03 it would be a good argument that they are bigger than the 04+ since increasing pump pressure would increase flow requiring a smaller injector.
