You can get #10 threaded inserts and machine screws at any hardware store. #8 might do too, but I stuck with 10 because that's the size of the normal neck screws.
If you want to buy online you could try ebay or Ed Roman sells a kit(though it costs way more than the hardware itself would, $20): http://www.edroman.com/parts/IS_specialparts.htm#DCK
Woodcraft has the inserts, but I'd stick with their 8-32 because the 3/8" pilot hole for the 10-32 might go through the side of the neck.

Machine screws are easy to find, you probably want 1-1/2" length, measure your neck pocket to see.
It's better to buy hardware in-store though.
great...
thanks nice info.....
