is this the right caliper for the GSXR swap?

thats not the one i normally use on my kits, < thats 04/05 stuff,
but i have made that one work also, i made a different bracket for it and cut that one the brace hooks to off
so, yes that one can be used
 
that is the one i got and used with awk08's brackets. i wouldnt buy that one yet though. they go on ebay for a few bucks in auctions without that bracket if you search around. i got mine for like $15 shipped
 
yes, thats the one, and looks nice and clean
 
Thanks for all the info! Turns out there a big motorcycle Salvage place not to far from me, they actually have alot of the Acutons on Ebay. Lucky me!

I was looking at the build pics for your '01, what brake line did you use? Just the stock GSXR one or did you pull it off something else?
