Apple II+ motherboard chips

Hi,

I just make a list of all chips in a Apple II europlus rev RFI (820-0044-D) and checked if it is possible to buy new one from Jameco and come up with this list.

Those having a price of 0$, I didn't find at Jameco. It is no new manufacture for those chips today? Could I use something else instead?

If I'm going to buy new chips today are there better version/options for some chips than the original ?

For example, I read that if I should use a 65C02 it's best to change some of the chips. (74F257 and 74F174)

What about change 74LS174 to 74HC174?
