67 Project - Update
I knew the '67 frame was toast but wanted to break it down and save/sell anything that was worth anything. Most everything was rusted to the point that the frame flexed when we lifted the body off. I photo documented everthing and began the bag/tag process.
Here is how bad the frame was, the PO had weld plates applied to half the frame just to keep it together.
I picked up a really nice '75 donor frame/rolling chassis and started to break it down as well... more ziplocks!!
I am converting the '75 frame to match the '67, so the body mounts are getting moved/transferred. I set up the frame, laser leveled and then set up a datum frame out of unistrut. This was really great as you can bolt it all together and still see the center lines on the reference holes and body mounts. Here is the way I sectioned the frame to splice on the '67 rear frame sections.
Here is the pass side frame section during pre-fit.
The '67 frame is wider and the '75 is taller so I had to cut out wedges and re-shape to mimic the original frame transitions
Here is the rear part of the frame all tacked up
Top welds done and ground smooth, I also wire wheeled the '75 frame - gotta love the new smooth/shiney steel!!
The inside frame line is nice and straight, I'm very pleased with how it's turning out!
I'm also full welding the frame and adding a removable trans crossmember that I picked up from Craigslist ($120). I'm fabricating the side rail brackets from the ends of the '75 fixed crossmember and modifying the front side tabs to match the 90 degree shape.
Last night I repaired the #4 body mount holes that had some rust wear and tacked in the patch where the fuel line exits the front kick up. I'll try and get some more pics posted as I progress. I've got all the suspension parts cleaned/sandblasted and rust prepped, just have to catch a nice warm day to get them primed and painted. I hope to have a new rolling chassis in a month or so.

As to the tranny crossmember, it will unbolt and drop down once the pipes are disconnected and pushed to the rear. I have a '91 World Class T5 and '83 Camaro bellhousing that I'll be fabbing up once the frame is rolling again.
Nice work on the frame! Question - where did you find the "83 Camaro bellhousing? . . . I haven't seen another one of those since I bought mine 3 years ago. A very rare piece!

Here are most of the suspension/chassis parts all rust prepped. I also got a bit more frame cleaning done with the wire wheel, need to vacuum up the floor a bit though. I understand that there will actually be a day when the rusty, grimey work will be done, one can always hope...
I meant to add that the rusty looking film on the parts is the converted oxidation and it just rubs off with a Scotchbrite pad. Next nice day will bring some primer work!

Here's a pic of the infill welds along the driver side frame rail as it meets the front crossmember. Once they are wire wheeled, you have a hard time telling it's not original.

Then scraped off all the undercoating and started to blast the front crossmember area
Found some stress cracks in the old welds that need to be fixed and will drill the holes for the '67 front bumper brackets. Also, did a light blast on the rear kick up covers and they are super clean metal, will finish the undercoating removal/blasing back there on the next nice weekend. The trailing arm pockets are very clean as well, nice smooth metal.
I will need to splice in a patch to the bottom of the #4 crossmember to mimic the holes and spare tire suspension rods, the '75 has different hole locations and a sloped area that isn't correct. I'll also get the bolt nut plates made and installed for the bottom part of the removable crossmember attachment.

The only area that concerned me was the sandwich between the lower siderail to #3 crossmember gussets. They had a bit of rust that I couldn't get to so I cut out the welds, sandblasted, rust prepped/zinc primed and re-welded into place
Here's a pic after wire wheel, now I know it's clean under there!
I'll post the removable crossmember work next...

I salvaged four 7/16" NC14 weld nuts from my donor frame and cleaned them up, you can use the sombrero nuts or the spare tire bolt nuts.
Then set the splice cut width, I set it 1/8" wider than each side of the nuts
Then drill the 1/2" holes using progressively bigger bits
Cut the splice out, I use a 4" angle grinder w/ cut off wheel then a dremmel/cut off wheel the get the corners
I put weld tabs inside the frame to strengthen the weld and keep the splice in plane with the bottom of the side rail. I grind out half round dimples for the initial tack weld, keeps the tack weld out of your main weld line and allows the splice to lay flat.
Tack weld the nuts, centered on the holes and bolt up to the xmember and test fit
Finish welding the nuts to the splice plate and then tack the entire assembly into place
Unbolt the xmember, finish the full welds and grind smooth
I should finish the #4 crossmember tonight and post those pics tomorrow...
