Jockey Wheels

Earlier today both my mech hanger and guide pulley failed, which resulted in a long walk home!
I've already sourced a replacement mech hanger but I'm unsure of which jockey wheels to order, my rear mech is a Shimano 105 on my 2008 Specialized Allez elite (9 speed).
Had a look on Chain Reaction Cycles Site, I don't know whether my mech is a top or bottom pulley, which jockey wheels would fit?
Can anyone help??

the top one is a "G" pulley.

Only thing was that on closer inspection my chain was goosed and the cage on the rear mech was bent too.
I ended up buying a rear mech hanger, chain, cassette (had to with the new chain) and a new rear mech, turned out to be an expensive week!
