Looks like the worst of the rust is around the leaf springs and hangers
Actually the worst of the rust is on the left front area.
Rear is pretty much just surface rust.
Left front had some serious flaking, hoping the POR15 will save it for a couple years.

Maybe for x-mas I will get a clean southern frame :D

Wow! What started out as a knock has now morphed into a restoration. Considering the mileage on the rig, you’ll end up with a newish truck.
:D That's what my buddy that I got the truck from keeps saying to make me feel better about buying this nightmare. I figure all the effort and money is not lost though, it will be a pretty decent truck when done.

Parts cost is approaching what I paid for the truck. :oops:

Hopefully the time and money you have invested will not only put you ahead on the value of the truck but a sense of accomplishment of repairing it yourself.
Keep us posted.

Got the replacement engine cover on, took about 6 hours, lot of work.
Also noticed more cracks in the old engine cover.

All back together, just need to torque the flexplate bolts.
Now on to replacing the bellhousing on the transmission.

Yeah, if it was a gasser, a Ford or Dodge it wouldn't be worth it 😄

Got the new bell housing on the Allison, wasn't too bad a job.
Now on to water blasting the frame and getting that done.

Yesterday, started putting POR15 on the frame.
Once this is done then I can start putting it back together.

Any idea what caused all of this damage?
Pic in post# 2 shows the corrosion that occurred in between the rear plate and transmission, it was about an 1/8th inch thick and had enough force to break everything.

Never seen anything like this nor has anyone I showed the busted parts to.
One contributing factor I think is the crap they put on the roads in the winter around here.

Another weird thing is the left side seems to be worse than the right.
I noticed more rust and corrosion on the left side of the whole truck.

Oh one more update.
I had picked up a old cheap flatbed with a wood floor that needed to be replaced but the structure was all solid. But I think it's going to be too light and the truck isn't going to ride good.
Guys that drove this truck before I got it tell me it went down the road nice.
I drove it for a short trip on highway with no bed on the back to test the new fuel lines and it was all over the place.
So I think getting a bed that's a bit heavier would be a good idea.
I shot an email to Bedrock truck beds in Texas and they said their Diamond series bed is about 1300 pounds. That put a little weight on the rear and help it ride better.

Day I got the truck at the end of March...

New fuel lines on and test driving before I found all the broken stuff.....

This is the bed I plan on getting... about $3k out the door.

I figure all I have spent on it why put a cheezy old flatbed on it.

Today's update, nice to be putting it back together.
Thinking about throwing a seat on it and taking it for a rip. 😄

Need some help. Mice stole the insulation out this heal shield/insulator that goes on the firewall.
Anyone know what is called ? I can't find it listed anywhere on the GM parts websites.
It goes where I snapped a pic, it was like a black fabric looking thing.

I looked up the gmpartsgiant site and found this:

The 303 number looks to be the one you need

That's what I was thinking but when I do some more digging it says interior left and right.
Plus it's like $130 if that flimsy piece of insulation is $130 I will pass and find something else to put there.

Some have used Dynamat or a high temp product like Dynamat

Working on the wiring 🤬 the last couple days and the left rear rotor replacement.
I think it's beyond spec.
Good thing a buddy of mine has a 2004.5 GMC LLY that I can get pics of where the wires go.
