This is the part list as it stands now, most should be easy to get a hold of from your local electronic component shop though you might have to consider other sources for the older parts such as CPU, memory and PIA. Personally I bought most components with free shipping from China via AliExpress, prices will vary though you should be able to find most components in larger quantities than you'll ever need for the cost of a few cups of fancy coffee! You don't need the newest and fastest components, it's going into a 70s-era computer so don't go overboard unless you want to (you can replace 74LS ICs with 74HCT or 74ALS if you want something newer). Most components have been produced by various manufacturers, these mostly do the same thing without any relevant differences though the choice of CPU and PIA could lead to incompatibilities so I've specified the ones I've had success with (probably also the cheapest ones available).

Some vendors will have the same ICs in different form factors, the ones you want will often be specified as being in the form of a DIP/PDIP package. Usually you'll want sockets for each of the ICs as well, a bag of assorted sockets should be easily available without setting you back more than a couple bucks. With the sockets in place, you don't need to dread having to remove an IC later, this leads to easier fault finding and you can easily "borrow" them for other projects later! For the pin headers, both male and female - if you can't find the exact pin count, just buy the longer versions and snip of the parts you don't need. Electrolytic capacitors have a max voltage rating, the cheapest are 16V and should be more than enough - you can use higher rated components if you want to, but note that these might be bigger and might not fit properly.
