ok so i'm a huge freaking dumbass

now that we got that out of the way, I had bought a turbo II that was partially finished from a guy and I finally had it all put together. But then when I went to fill it up with coolant, it all pretty much burped out after getting it partially filled. Paper towels and several minutes of cursing later, I find that the previous gearhead negleticted to put the a bolt in the water pump into a hole facing the intercooler, close to the coolant bypress line, which goes up into the BAC. So now I've got a partially filled turbo II with a missing bolt in the water pump. If anyone can give me some specs or pictures of the bolt I'm missing that would be great. I think I've tried to see if I could use the top bleed bolt from my radiator but that won't fit.
