D25 Voltage Regulator cross-reference?

[bamfordsgarage]

It appears the voltage regulator in my '47 D25 needs to be replaced. I troubleshot the charging system more-or-less per the manual, and Condition 1C (below) came up the winner — a jumper wire brought the charging system to life.

 

The manual calls for an Auto-Lite VRP 4503-A (35-45 Amps @7.2 to 7.5 volts). I'm trying to source this locally or at least in Canada and have come up empty thus far.

 

I recall a page on this site several years ago that listed part number cross-references for various components. I can't find that page now, so either it has disappeared or I'm showing my age.

 

Can someone please help with alternative part numbers for this regulator and/or advise where the reference page is?

 

Thank you.
