You also have to be careful with the antenna ground. If you mount the
modern neg grounded radio on a block of insulation,in a Pos ground car, make
the correct power connections, and hook up the antenna, the antenna shield
will light up and remind you to use a fuse in Both leads for the next radio
you buy, and cut a notch in the antenna line shielding.

Joe :
Modern units are smaller, and don't require ground isolation. (IF you can
completely isolate the ground, you don't need a converter at all, just an
extra
fuse.)
JCW lists one that is a 1.25" cube, rated 50watts continuous at 12v.
Still a poor solution, IMO. Much better to convert to negative ground.
