OP Amp Dual General Purpose ±22 Volt44 Volt 8-Pin Plastic Dip Rail

is actually a MC34072P, and the

OP Amp Quad General Purpose Rail to Rail I/O ±6 Volt12 Volt 14-Pin Plastic Dip Rail

is a MC33204P.

They may be replaced with TL072 and TL074. They should be easier to source and have the same pinout.
