You can appreciate the “beef” of the GMC/Chevy 3500HD trucks, a stripped rolling 3500HD chassis weighs more than a running C1500!
When posting on this site you won't have to explain what the 3500HD Beast is! ie 19.5 wheels, straight axle, 10 bolt wheels, 15000lbs GVW etc

Had another reboot today (12/14/17) 10PM so I lost posts from 24hrs ago. Was trying out some new themes when the page went down...had to load the 24hr old backup.

Sorry...but almost done moving this site to the upgraded server.

Attached some pictures...but realized you aren't building a dump body so my setup won't work for you.  Maybe you could make it a dump and install hydraulics later?

Yep slow boat
you saw it too. It seem Previous owner welded a goose neck plate to the truck  frame the welded the  flat bed to the goose neck plate. When they separated the flat bed from the truck frame they cut the plate from the frame and left it welded to the flat bed. That box is not strong enough to tow from. Im cutting it all out tomorrow I didnt realize how it was all put together until I flipped it over.
Thanks for the input. I will use the box as an access hole only and install a plate and ball if I ever go goose neck.

My 99 HD (454) needs a new muffler and I need the pipe that runs from the cat to the muffler (160" wheel base).

I called NAPA and the dude told me there's no listing for the muffler.

I went online to NAPA's website, and they list a muffler, but the picture shows a different muffler.

Does anyone know where I can get the muffler and the pipe from? Also, might anyone have part numbers?

I found Walker's muffler, part number 21400. Picture appears to be correct. Can anyone confirm?

In looking at the inverted bed pic, I noticed that the gooseneck ball is mounted in the bottom of a fabricated box.  Can't tell how heavy of metal that the box is made out of, but didn't see any bracing of the box to the rails or crossmembers.  That would put a lot of stress on that box itself.  You might want to consider some bracing to the main rails and crossmembers to prevent a collapse if it does ever get used.
