STICK YER PENIS IN IT!!!
Dude just call Rippmods or Toyota and get the thread size then hit up home depo and get 2 galvenized steel bolts to plug it.
...btw I need Chris's email addy asap, I need some $$$
[edit]
...now that I think about it... are you sure you didn't have the plate in the first place and Lightspeed didn't just forget to put it on, like they did with your cat. ??? Perhaps they didnt think the bolt holes went all the way thru and since its not a nessesary piece they didn't bother with it.
I'll check pops's Cam for ya tonight on my way home.
