ooohhh baby.
why/where you get that from dave?
i may not need to borrow it if i can call you and just get a few dimensions off it over the phone.
I suspect its quite close to perfect (according to rear brake plan 34B) so am still after a set to keep... anyone?

http://forums.toymods.org.au/index.php?t=msg&t h=44197&start=0&rid=92&S=9cedaddd10e82 3383283f778b39fa99c
second hand or new, doesnt matter as theyll be used for rigging up an assembly, and designing other bits.
must be from the single piston caliper model (most of them will be)
specs are:
307mm dia | 67mm height | 16mm thick | 190mm handbrake drum
may also come off:
SOARER / LEXUS SC300, SC400 JZZ30 JZZ31

Well, I found a pair at the wreckers. DBA didn't have them in stock until only recently and Toyota want about $470 per rotor for them.
Or you can call me, but my Verniers are on the other side of town at the moment.
