James,
The front disc brake stuff is discussed in this thread
https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=603612#Post603612
Probably best to move discussion of it to that thread so as to not confuse this one.
But in short, just like this 14 bolt swap, I haven't done any more than decide it'll work... But I don't like having to use the expensive original front wheel bearings, and until I find an alternate solution I don't plan to put anything together.
Also, I'm not sure the front rotor and caliper I picked out fit an original 17" wheel, they do fit a 19.5" however.
