I replaced the 48 year old (original & working) start and horn relays on my 1966 Coronet 383 4bbl automatic. Here is some info you might find helpful - not sure if these p/n's translate to other years though.
Start Relay - Mopar p/n 2444 442
Standard Motor Products p/n SR-105 - (almost identical to original)
Echlin p/n - ECH SR5
Horn Relay - Mopar p/n 2291 436
Standard Motor Products p/n HR-135 (note- physically looks different from orig. but will work)
Echlin p/n HR126 (not sure if this is still a current p/n - found an NOS Echlin relay - it's almost identical to an original)
AC DELCO p/n - C1746A (have not laid eyes on one but the SMP & Echlin p/n's cross to it)
Note - start relay info correct for '67 also.
