Seeking Factory Cummins 8.3 Injector Info

Does anybody have a loose injector out of an M939 series Cummins 8.3 engine?

I am looking for the info imprinted on the nozzle of the injector. I am having some custom nozzles made for a new set of injectors on mine, and need to know the factory nozzle hole size and spray angle, which is described in the data on the injector nozzle.

I could pull one of my injectors, or just order a single new nozzle from Cummins using my engine serial #, but it would be much easier if somebody already has one rolling around their tool bench.

Thanks.

I will hopefully have them out of my 1991 M932a2 tomorrow. If all goes according to plan, I will post the info tomorrow.
Any updates here? Sorry to push, but I am hoping to place an order tomorrow (Monday), and the stock injector size would be very helpful to know as the starting point. I could pull one of my own injectors, but if somebody else was doing it anyway, or had one out already, then chicken dinner.

No, sorry. Got a ton of rain here yesterday. Trucks outside so rain put a stop to working on it. Post your question in the "So who has bumped the power on a 6CTA cummins" thread, I'm sure someone there will have the info you're looking for.
