Relays would be standard four-pin automotive relays (Bosch, Hella
etc) as would be used for auxiliary lights.  For the diodes, I'd
expect these to work:

Barrel Diodes Model: 1N5404  |  Catalog #: 276-1144 from Radio
Shack.  For the resistor I'd suggest measuring the one in the
existing relay, and using it or a replacement of similar or larger
physical size -- and/or contacting Mr. Atwell for advice.
