WA WTB or Locate AC Delco #18M1036

[samkost]

Wanting to buy or help locating a new old stock AC Delco part# 18M1036 Master Brake Cylinder pictured.
AC Delco has recently changed the design style of the part from the older OE replacement style pictured.
The older OE replacement parts have the double wire bails for the reservoir cap.
The newer replacement parts are a different master design with on length wise single wire bail.
They have not changed their web photos or packaging but still retain the
AC Delco part# and the GM part#.
Web site vendors are not offering this older OE style master.
Thank you to forum member 1970cstblazer for the first reference photo.
Thanks for any info, help or leads.
