I ended up picking up a new set of these calipers for almost nothing so I am going to see if I can make an adapter to mount them on my 3" spacing Boge 911 struts.

These are 5.25" bolt spacing and are listed to work with the 911 rotor thickness and diameter.

No guarantee this will work but we will see....

I don't see it happening. Unless there's enough offset to allow material between the 5.2" spacing and the 3" spacing. Hard to tell in the pics, but it doesn't look like you'll have it.

Contact Flat (Lanner), I think he lives in Fort McMurray now, he's a master at adapting calipers.
He also makes a kickass carb cable linkage kit.

Thanks for the recommendation but I want to try fitting this myself. Barring the steering arm or stock mount physically blocking the caliper placement/offset it should be be pretty straightforward. I have access to pretty much anything required to make a set of adapters (Solidworks, cnc mills/lathes/plasma tables, mig/tig etc) as well as some pretty clever guys.

Check out this thread....my Wilwood conversion is detailed somwhat in post #20....go for it, it's not rocket science. Beware that you'll need an adapter for the brake line since the Wilwood uses non-metric threads.
