I would like to give a huge thanks to MAZ (Mark) for the wonderfully detailed post he had here-

Generator Radiator Modification

since I don't think there is any way I would have had the cojones to chop off the engine frame supports for the radiator if he hadn't done it first. 

I had some unistrut parts lying around so my installation is a little bit different but with the same ideas that Mark had. 

Rather than reusing the chopped off radiator frame which had some really mangled radiator mounting holes that someone before me must have tried to enlarge and/or move, I scrapped it.  I used 2 unistrut base mounts

with 2 90 degree brackets attached to it.  These are extremely common building materials if you are an electrician, plumber, or HVAC tradesman and are available at Home Depot or supply houses.

Depending on where you drill your base holes you will need to make adjustments with unistrut square washers to get the fan shroud centered on the fan.  Rather than trying to reuse the 16 year old hardened rubber radiator isolators, I modified a couple of soft neoprene expansion plugs from the hardware store for vibration absorption and the radiator sits directly on top of them with a screw coming up from the bottom of the 90 bracket. 

On the radiator air intake side, I used 2 pieces of all thread with a coupling between them to make the essential supportive 3rd leg and the coupling in the middle allows me to take everything apart quickly, if needed. 

I replaced my Cummins primary fuel filtration setup and had the old filter base leftover so I decided to use it as a primary fuel filter on the generator since my FT only had the on engine filter when I bought it.  It mounted perfectly to the 2x2 steel frame member right next to the generator with a u-bolt similar to this one (this is not the right size so don't use this part).  This primary fuel filter can be seen as the red Baldwin filter on the outside left of the generator enclosure.

I wanted to add that at 1100 hours on the generator, the valves were all much tighter than the 0.020 specs called for in the manual.  This is quite easy to do on the Isuzu generators and is supposed to be done every 1000 hours.  Maybe your results will be different but based on how out of spec mine were, I'll probably be checking every 500 hours.
