i have a MV104 and MV1650 both varactor diodes , can i use these for replacement for BB329?

thanks a lot. they still sell these ic's here in the philippines. good thing they have it. but in case these aren't available here, what can i use as a substitute?

i am a newbie here and i need help guys. i have a school project and i plan to include this fm circuit with it i am supposed to control the radio with my parallel port but the problem is i can't find the parts BB329 and BB105. any suggestion for a replacement for these parts? thanks in advance
