I've just ran into my first, very minor hiccup.
The supplied bushes, which I specified as upper shock mount for AU live axle are wrong.
The Nolathane part number (poly) - 43023, and Kelpro part number (rubber) - 23023, have an incorrect boss size of ~14mm.
They have the same listing for all E series Falcons too.
Someone has made a big stuff up.
I may need to go genuine Ford for the rubber ones, and for Poly it looks like the Superpro ones are on the money, with a 20mm boss.
Part number - SPF0204K.
GK - Thanks for the kind words, the cheque is in the mail.
