Have heard similar stories as you've mentioned above
IMHO just reco the front end as per original with exception of the brakes -- the alignment can be tweeked for better performance unless you're racing it
BHSS / TBS Capalaba (Brisbane) do brake kits for these- rotors, hats and calipers etc
She'll be good for another 50 something years then

My experience (and its not right or wrong, just what I found) - I looked at the wilwood kits (and spoke to them), general view is that these are fine for street/show but anything more they are a little light (of course, wilwood have other beefier options, just talking about the "big brake kits" - although it does have the dust boot option). FYI, mine is just a fun/track car, not a cruiser.
I ended up with Hoppers gear as they could do the rear as well (new kit, which is basically from BHSS/TBS), much heavier rotors etc etc - I am yet to get it out in anger but certainly seems like its up for the challenge. I did speak with BHSS and they could supply a kit but only if I supplied the wheel/hub etc so they could ensure perfect fit, hard from WA but in retrospect this should have been what I did - if I lived in GC/Brid, no brainer.
FYI, I have ended up moving to 16's to clear the new brakes - after all my measurements etc, I still stuffed it up (15's cleared, but talking mm's)
Summary - you have one of the best shops close by, take it in and get a package for you (and you won't need to stress over offsets, size etc)
cheers
