possibli:
C451G = uPC451G = LM324
uPC451G (web)
uPC451 datasheet

equivalent:
LM324 (web)
LM324 datasheet

NB: check the wiring, specally @vcc/vss to ensure the same pin-out
also, since this is an OpAmp, you may see input/'feedback'/output which may confirm the chip layout
----------

The 4066 is pretty obvious a logic chip... a "Quad Switch" to be more precise...
on your case, it should be Toshiba TC4066BF
here the data:
TC4066BF (web)
TC4066BF datasheet


solved by the help of the mighty google

sorry for bad english
