1974 Dissection and Rust



Frame cut into four sections. From left to right the front section is usable. The second section with the manual transmission cross member is usable. The kickup area is not usable, rotten. The rear section is usable.
Section picture of the frame dissected.
Rust removed from the 74 frame. Weighed in at 9 pounds, 14 ounces, or almost 10 pounds. Also found a critter nest in the frame.
Someone before Gregg tried to hide the rust with expanding foam. Interesting use of foam.
Cross section on the drivers side.
Cross section on the passenger side.
Section three, the lower kickup section, is toast.
Both sides.
Pocket is okay but not the kickup.
Both sides.
So once again good call Gregg, you did a smart thing moving on to a new frame.

I tried running a coat hanger thru my frame and hit resistance at several locations.
I now believe that the hollow box frame has several reinforcing bulkheads, as marked, so it is difficult to get the Eastwood frame coating tube inside, for one. Duntov's book mentions them as preventing the frame box from collapsing under load, particularly in the "S" bend.
Could you confirm their qty / locations? Maybe even get a picture of one?

First, thanks for your service, I was in during the 80's myself.
Second, what is your opinion of the Eastwood frame internal coating? I used it pretty much throughout my frame as I am rust-phobic, but have heard various opinions about using it.
I did an especially heavy coating in the birdcage by snaking the long tube up from the front kick panel areas, along with the main frame cross members an of course the kick up area.
Since you seem to know a lot about frames, I was wondering what you think of it.

I use the Eastwood frame internal coating on all of my frame work.
Once the coating is put in place I believe the internal rusting is slowed and or stopped.
I see it as a key to keeping frames on the road as long as possible.
I'm for it.

I removed the passenger side rocker trim for the first time last week to gain access to a couple of bolts and discovered the frame # and date. Didn't even know it existed...didn't wipe it off, just kept the 50 years worth of dust and dirt intact.
