Rockclmbr- I like the "indexing" latch- is it spring loaded, and did you make them or can they be purchased as you are using them?
outsidelc- I can't answer where Rockclmbr got 500 pound slides, they look beefy! I did mine with 250 lb slides from lee valley hardware, and have been more than happy with them. A drawer will hold all 200 lbs of me, and they are full extension, so all but about an inch of the drawer comes out (mine are full length to the back of the middle row of seats). The slides are here:
