Incase anyone is interested there are several 2 quart oil filters available that's actually for early model small and big block Chevys, and many other vehicles with the same threads and diameter as the OEM Duramax oil filter, but longer
here's 2 that I was able to easily find specs on.
They don't have the by-pass valve which is set to open having 15-20 lb springs, IMO is a good thing not having, possibly returning dirty oil to the engine, also they don't have a anti-drain back valve, which concerned me a little with possibly having dry starts after setting.
With the angle of the oil filter this has not been a problem, and no-longer a concern.

AC Delco PF2232 30 micron OEM $9.00 @ Amazon - 2 qt Ac Delco PF932 30 micron $10.50 @ Amazon - 2 qt Donaldson P550832 20 micron $11.50 @ my local Empire Cat. which is a Donaldson dealer.
The Donaldson is a little harder to find for a good price, but I like the oil drain-back on it compared to the AC Delco PF932, which led me to start off with the Donaldson, making it now a 11 quart capacity having better filtering.
Oil pressure is just a few psi higher, a little harder to evaluate with the much colder temps we now have.
