Does anyone know of a rear disc conversion for a '73 sportster that does NOT require frame or swingarm modification?

Easiest way is use a 79-81 sportster swingarm, brake and rim. .bolts straight in i believe. I'm currently putting an 02 fatboy rear rim with a 98 sporty 11 1/2" rear disc setup on my 77. ..a little more involved so it has turned out but getting there. Havn't seen any pics of one using the standard swingarm to comment on?
