Almost all speakers came in standard sizes. Mounting can
be different but often adaptable. So rob another radio !
When you start changing parts do it one at a time & test
it as you go. This way if you mess up its easier to find
what went wrong.
For the SW it probably has a separate antenna. If so just
hang 20' of wire off it. A weak converter tube may not
oscillate at the higher SW freqs but still work OK on AM.
Also remember this is a HOT chassis. In other words the
metal chassis is hooked to one side of the AC line. If
you dont have an isolation transformer be very careful
nothing including you touches ground !
Good luck with her.
