Just an update with part numbers to this thread.
I think it helpful to share the part numbers rather than "I put a Griffin Radiator in mine" which is as helpful as just saying "I put a piece of metal in mine".
My wipers were embossed with "TEX" logo.

They're stainless and accept a 5.2mm bayonet type shaft.
Industry Part number GWB219, or TEX PN B05110 (natural), B05110P (polished), B05110E (black)
Came to $34US total for two incl shipping.
Construction quality much better than Trico or the ones Moss motors sell.
