Hey George, can't seem to be able to pm you yet since the change, i can email some pics can probably do that arm for $15 + post or the whole hicas rack for $30 + post.
My email is vlto3@hotmail.com or can call/sms 0402947743.
Also have an rb30 motor laying around, series 2 a6 block with turbo pistons, ran well but developed a slight rattle at 2500 rpm.
Head has been removed and manifolds.
$80 for the block $60 for the head, only pic i can use at the moment having problems with attachments.
