Just got a 76 for my son and i to do a frame off. Any advice before we begin?

 

A real good smokey burnout with pictures is always a good start!
Seriously, that looks pretty good. Take lots of pictures and get small containers for nuts & bolts and label where they came from.
Tag and label all of the wires. And everything else small.

 

Welcome to the forum. Also tag all the hoses and where they go. If it has A/C and it's still functional and filled with R12, you might try to get it recovered because it would be very expensive to replace it, if you can even do that now.

 

I forgot to mention that you'll need to get a lot of rust penetrant like PB Blaster or Kroil to soak the eight body mount bolts. Even then you may have to resort to cutting torch or sawing.

 

Invest in a Coil Heater for rusted bolts and plenty of knock her loose, Another good investment is a Impact either air or cordless.... Take plenty of pics when doing the Removal so you have a reference when you put things back, And You Tube can be your best pal....Most important is a service manual.. I have mine on my phone from Wilcox and print as needed.....
