where to get type A relays?

[Jasminka]

Engine conked out a week ago. Eventually found it was a bad relay, by swapping relays around.
Now the original Bosch relays are 4-pin normally open with resistor, but have the type A pinout.
Now most places (Autobahn, Repco, Altronics et cetera) sell the type B relays. Even worse, one
brand does not say on the packet what type it is, and it is hard to see the moulded numbers
besides the connectors.
So where do you get them beside Holden dealer or specialist auto electrical supplier?

Repco was fine getting me a relay that matched, even the 5pin half size was no issue. I took in my old relay to ensure the numbers underneath matched the new one. Last relay was from Holden.
