Occasionally I've seen older BL radios pop up on ebay, so you can look there.
JC Whitney has a converter too. My dad had one years ago on VW Beetle he had,
and I'm pretty sure it came from JC. I just looked and here's a link to
several:

You still need to be very careful about isolating the radio from the chassis.
Actually if you're really careful you could probably do without the convertor
and just wire the radio + to the chassis and radio - to radio power. You have
to make sure that the speaker leads are isolated - don't use the chassis for
speaker - (or + either!). All modern radios I've seen for quite a while warn
against this anyway. Also watch the antenna. The base of the antenna is
usually connected to the ground (shield) on the lead. Be careful you don't
end up with a short through that lead! I'm not really sure how to handle
that. You might check with Radio Shack too, though I can't find anything on
their site right now.
HTH!
