Why not just cut the can and use it to house the replacement caps. Post 12 shows the spot where the wires are soldered, that is one side in the pic, the other side is the same spot one the board, just follow the trace, the runs are a mirror image. If you need a clearer pic I can get one, just means I have to take it all apart again.
I think you will be happy with the sound, I have mine running Dynaco a25's.
OK got ya, I'll shoot some pics for ya.
Here is the adaptor I made for the 63mm cap, will be replaced with two 25mm caps
