Default XJ40 vs. X300 Fuel injectors and fuel rail

I have a '90 Majestic as my DD and I have an X300 4.0 fuel rail and injectors in my parts bin.
All of the part numbers are different between the XJ40/X300.
Does anyone know the differences between the two sets of parts?
I'd like to use the X300 parts as spares for my Majestic; can I?
Thanks,
Roger

The injectors are different. From 93 they use a dual path spray. I tried using 94 MY injectors in my 92 and it set the engine light off. Plus, the aj16 motor is a coil on plug motor so the injectors are probably different again. As far as the fuel rail itself I suspect the connections are different maybe as simply as pointing at a different angle....

Thank you Jerry!

Anyone interested in six (6) X300 fuel injectors and fuel rail for $75.00 and I'll pay for the shipping?
