3/4 ton stepside dually

[98Murray]

Hi guys and gals. I have a nice 1985 GMC High Sierra 2500 with a 454 and 4 speed standard, 2WD. I am wanting to turn it into a fun little daily driver that can still haul things when needed. I have always wanted a shortbed dually and I have always liked the stepside beds used for these year models, so I want to kill 2 birds with one stone. I need to figure out how to get the dual style wheel on the front but for the rear I was going to find add the parts from a Cab Chassis dually which, I believe uses the same 14 bolt but with different backing plates brakes and hubs, correct me if Im wrong. The cab chassis duallys are mush narrower than the true duallys so I think they will tuck under stepside fenders or be very close. As for the stepside, well that will require a bed and some frame chopping. Quite an ambitios project honestly. Kinda looking for some opinions and suggestions from yall. Heres a photo of my GMC and a photo of kinda what I want to build.
