Kid, no adapter is needed for Wilwood Superlite 2s in front- just a thin shim to center the pads, but there are complications. The hole pattern in the Wilwoods is spread wider apart than stock Girling calipers. You can use the upper stock hole and bolt, and drill/tap a new hole at the correct location for a stock bolt. It's been a decade since I did this, but I think you'll have to ream out the Wilwood mount holes a bit for stock Pantera metric caliper mount bolts.
When you drill/tap a 3rd hole, it often gets dangerously close to falling through the steering arm bottom. The steering arm is forged steel, so a little judicious welding and filing on the bottom of the arm near the new hole will build up the area so it won't crack. Don't attempt to speed up cooling of any welds here. In any case, braking force is mostly upward so not much force is added to this area but if the new threaded hole gets close, I think its still a good idea to reinforce it a bit. And obviously, the stock french-lock plates won't fit the new bolt spacing either; I safety-wired the bolt heads together and have had no trouble.
