I am also currently working on a 42-380. I am replacing the 8-8mfd dual electrolytic with two 10mfd 500V electrolytics. I am replacing the 18mfd electrolytic with a 20mfd 500v electrolytic.
When exact values for capacitors are not economically available, my general rule of thumb is to use the next higher mf value available and match or exceed the voltage rating. These older electronics have pretty high tolerances.
Since the original part is a cardboard tube under the chassis instead of a top mounted metal can, I wouldn't worry about stuffing caps. That is, unless you think someone is going to disassemble the radio to see if you did a good job of restuffing the cardboard tubes.
My radio came with a 6X5GT in it, and the power transformer windings have good resistance readings all around. I think the hullabaloo is more focused on the 6X5G rectifiers. I've not heard anything bad about the 6X5GTs.

It's not how bad you mess up, it's how well you can recover.
