Default Torx size for supercharger idler pulley?

Hey guys,

I've been sick for the last week and a half. Probably directly related to my trip home in which I lost everything but the bearing and bolt for the grooved SC idler pulley (the one closest to the radiator). Was just wondering if anyone knew what size Torx that bolt is, since I don't have any tools with me and would like to expedite my trip to the store so I don't go crazy in my sickness and buy a lot of stuff :P Managed to get the replacement pulley, and that came with a hex head bolt, so that wasn't any help.

Much appreciated.

It is very nice to be driving this car instead of my truck. I've got a 14 hour drive coming up! Woo! (What is it with this car and bad pulleys on the SC belt? Jeez. Only original ones are on the crank and the SC itself now)

I had to dig up an old thread to find that it was a T50 bolt for both the SC tensioner and idler pulley. Also, the tensioner bolt has reverse threads. Here'* the post that has the info:
