Ok so i completed a yugo build about a month ago and its been sitting in my safe without a FCG in it. Im wanting to finish it with the required american made parts so its ATF compliant. What parts do yall recommend that are cheap and easy to install. Im thinking, floorplate, follower, trigger, hammer, pistol grip. what else?

And is there anywhere that i can buy this all at once for cheap.

Check out the Ak parts section of the equipment exchange.  Here is one that caught my eye.

a tapco G2 trigger group (3 US parts) plus a US Slant break for $36.99 from DPHarms

Add a $12 pistol grip in your choice of colors and you are set.  PS Leave the mags out of this, that way you can use any mags without worry.
