From a MTBR thread on the subject:
"As you probably know the quadra and indy forks have interchangeable parts and crowns ,I've cut out the lightweight indy sl legs and put them in quadra legs internal depths differ and I had to cut down the indy stanchions from 27cm to 20cm this makes a real lightweight fork in hindsight just shortening the indy legs may of been a better option the indy sl offers the most tire clearance, other alternatives are the aftermarket braces on mag series models etc. If you like to recycle older forks and need disc brakes consider the early judy forks. Early sid fork stanchions will fit in older judy crowns if you chop out the top"
