I spoke with Mario at Spectre yesterday, they have one style available. Part # 282-62 for just under $190. I looked all over the internet sent emails and made phone calls, flares for 60's and 62's are hard to come by! I decided that I needed a set to go along with ARB sliders, should be getting them in a week or two!
There was a thread on here about a year ago of a guy who found Nissan flares (Patrol or Xtera?) from the junkyard that fit pretty well. As I recall they looked pretty good and were cheap. I think they may have also been somewhat flexible, as some were worried the replacement fiberglass flares could crack.
