I have a 99 chev with a 7.4 and after it is started & warm it starts hard. It is ok until it sits about 15 minutes. The local dealership has checked injectors, fuel pressure, compression & the pressure regulator seems to be dry. We are scratching our heads. Could it be the regulator is bad but not leaking externally?

  I have no direct experience, but everything I have seen indicates Silverado and Sierra bed geometry is identical.

- 2024 Silverado HD shell on a GMC fitment??
  
  By cseaman · Posted 40 minutes ago
  
  Has anyone had any luck swapping a Leer or equivalent shell between the current gen GMC/Chevy HDs? Hopefully specific to the standard 6'9" bed. I had an Overland Vehicle Systems shell on my 1500 AT4 and I know those fit the Sierra and Silverado, with or without the Multi-Pro tailgate. That said, I think the Leer shells are made to fit all the way over the bed caps as opposed to on them with some room to spare like OVS. Some 1500 owners reported some change in coverage over the rear tail lights..but that's 1500 specific.
