the best thing to do to fix that front drum problem is to convert to front discs, as the drum brakes aren't much chop, in my opinion. the easiest way to get a bolt in fit is to find either a 1200 coupe, or an australian assembled 120Y with the Paton PBR brakes. Both of these will bolt in, with the only change being the need to change the rear wheel cylinders to 11/16ths. You could keep the original rear wheel cylinders, but the rear shoes will wear out quickly. You could also get the ball joints, tie rod ends & the idler arm & castor rod bushes changed at the same time. For about $150( used to be $100) you get a new front end.
As for finding a mechanic in Bendigo, my suggestion is to contact your local car club, & ask them to recommend somebody. I've looked on the CAMS web site & there's a BENDIGO CAR CLUB INC the contact name is CRAIG BUTTON on 0427 511 158 . There's also a website -
