transmission missing bolts!

[dysfunktion]

Ok so today I lifted my car on a rack and was able to get a good look underneath and to my shock, I found that only 4 bolts were holding my transmission to the engine. Although I should have expected it after changing my diff and finding only 3 bolts holding each axel to the diff. So anyways, I was wondering if anyone happened to know the size of the bolts needed to mount the transmission to the engine? I didnt get a chance to measure the ones that were there and wont get a chance to lift it again for a while and would like to be prepared with the right bolts.

on the bellhousing they are different lengths as well. when i did my 5 speed swap i just bought these, way overpriced, but they fit and thats all that mattered to me.
