YEah I looked at the redline web page
( "http://www.redlineauto.com.au/manifold.htm" )
and they only list stuff for webbers.
will try and find a local stockist in perth and give them a call though. i recall now on the back of a street machine mag an ad for redline with a twin su manifold advertised with a perth number. have to go and buy one I guess now.
edit :
ps what does DCOE mean??

These so called performance shop pepole who sold you the wrong bits need a visit. Go back and tell them they sold you the wrong bits if they still refuse you a refund tell them that they have big windows and therefore cant afford to scam people like you. DONT TAKE SH1T FROM ARSEHOLES LIKE THAT. If they sold you the wrong bits they have to take them back.
TAKE #### FROM NO ONE!!!

what does dcoe stand for?im not to sure what the d stands for,but i'm pretty sure the coe stands for competion horizontal evolution.if this doesn't make sense,try these words in italian,which is competitione orizontale evolutione.so,can anyone guess at the d.what's italian for carburettor?

The prefix number on the DCOE is the diameter of the throttle plate (the throttle bore) in mm; DC means "doppio corpo" (double throat); O means "orizzontale (horizontal); E means it is a die cast carburetor; and the number or number and letter suffix is the variation type. Except there seems to be several variations to most variation suffixes.
