I paid about $40...its a guess, As I got that and a whole lot of other things at the same time and they didnt itemise the bill!

I got it from pick n payless in Syd...like most places where you pull it yourself, its going to be cheaper...and in my case I wanted to get some of the attaching bits aswell.

I have seen brand new ones on ebay for $250.

As for the difference in pulley size....yes I measured it and the falcon one works out about 15% smaller..so it'll be going 15% faster...not a big deal.
I have a GD1021...so if roadhog is right, then I am on the smaller engine pulley anyway, and my alternator would have been going slower than it does on a Gd1022.

I dont know how much difference there is between the two...but if you own a GD1022 it may be worth swapping the harmonic balancer with one off a GD1021 if you plan on doing this mod.
I only have FE3 harmonic balancers, and they look smaller again (but I havent measured them) which stands to reason if they are, as the FE3 engine revs harder.
