also, there are some 4bt applications that used the saginaw style pump with no vacuum pump.
here is one

i think the fritolay box trucks used them and maybe a f-700 type ford maybe?

I'm trying to get a better understanding of what the problem is myself (not that I'm doubting him in any way.) In looking at the builds here, it doesn't seem that that assembly has been a problem for any of you, but most of the issues arise on the right side.
I'd seen the pump on eBay already. I also found a lead that led me to RockAuto to validate, but a 1989 Chevy P30 vehicle does come with a 3.9 Turbo Diesel engine option. They have the steering pump numbers, but they don't have any listing on the actual adapter.
The other thing I've found is that some commercial applications of the 5.9 did offer a steering pump, but those get even pricier.
Example
So, I've done as much homework as I can on this tonight, send Randy an e-mail and we will see what he comes back with tomorrow.
Thanks again for all your insight & information, as a Cummins newbie, I really do appreciate it.
