Size of drain plug for motor oil and bolts for transmission pan

[jsnowbordr47]

I'm doing my Senior Thesis for Graphic Design, and my project happens to be creating a how to guide for fixing and maintaining the 1995 Suburban. I've already done all the jobs and documented the photos, however I've forgotten what size wrenches I used for the transmission service and the oil change.

I'd go out and check the sizes myself, but I'm back at college (I do all the work when I go home) and I don't have my wrenches on me. So if anyone knows off the top of the head the size of the drainplug for the oil pan, and the size of the bolts for the transmission fluid pan that would be awesome.

Thanks

Engine oil drain plug would be a 9/16 wrench and the tranny pan bolts would be 1/2 wrench.
