I don't see anything there that would derail the project...you actually had less to cut out and repair than I did.
I didn't see any detail photos of the spring boxes or "B" pillars (behind the doors). These are critical to the structural integrity of the car and really must be solid. I did see where you had successfully removed both rear springs...that's a good sign. One of mine came out only after cutting the spring box in half...rusted solid. I wound up replacing both bulkhead halves (and triangular braces), both spring boxes, and had to fabricate the "B" pillars.
I noticed you used patches for the sills. As long as you got really good welds they should be fine.
I did not see any door bars to maintain the door openings while the cutting and patching was going on. Are the last photos on the list the most recent? If so, the doors look good...if not, you might want to test fit the doors.
I'm doing a '62 that didn't look much different...just a bit worse. Details are at the "Spridget Project" link at
