Bob, several guys drifting run billet spacers wheel hub adaptors with different patterns to suit 4 into 5 stud so you could run any cheap old ford falcon or holden 5 stud wheels which often come in many flavours.

Depending on the pattern holden of Ford you have to choose once you see what your needs are but Ive seen 13 x 8 hotwires for next to nothing on gumtree and at worst there are some second hand wheel & wheel reco joints in melbourne like "Steves wheels" that carry hotwires and jellies of those sizes already reconditioned (around 80-100 a wheel) - I prefer the hotwires as they are lighter than any wheel ive picked for that size. There are some holden wreckers in preston/coburg that carry those wheels also in those sizes and gumtree often has old toranas and other fords with them.
