First of, I was able to open that darn capacitor block. I am not sure why it was refusing to come out when the whole thing was bubbling, the paper was not tarred, it was a regular wax paper. Anyway, I decided to heat the seams, then brushed of the solder and separated them, and then open the whole thing up and removed the cap block.
The can looks like a croc. Or an alligator. That is their head when it is sold separately in souvenir stores.
Some pics.

The alligator.
   
The electrolytic bottom.
I used a copper-plated rivet mandrel (very stiff) and re-used original soldering lug.
   
Then I glued all together (with caps inside and some plumbing parts to keep the cap sturdy)
   
   
And put it in place. The seam is covered by the clamp so it cannot be seen, all you see is the body and the original soldering lug.
