What’s your plan


You going to put the GMT400 on that chassis and build something?
Yep, the frame on my 97 C3500HD is paper thin and ripped in a few areas. To fix either I burn 100+ hrs of rod and wire to build it back up, and fab new cross members.. or swap to a 800/900 chassis. And I can either leave it a 454/NV4500 or swap a dmax Alison.
I've still got my 19.5 that fit the 800/900 dually hubs. I loose a little in braking but gain a lot of availability of service parts. Plus I can move the parking brake from tail shaft to wheel hub
Used drw axle can run upwards of 4k
Outside snagging few parts nothing major is going to happen with this project

Well LMM has thrown a P0101 MAF code 3 times, all at idle in last 2 days.

Still running OEM air filter setup.

Hmm

Swapped in a different MAF sensor time will tell...
If not.. well there's tuning

Well that causes a nice vibration at 75..
Got almost 10k miles out of it

Searching for beds...
Found this picture in a FB add
Looks like LML/L5P bed on a 800/900 chassis
