This conversion has been done by a few people. Most notably it has been done by Brent Franker (who documents his installs well enough to write a "______ Install for Dummies" handbook on them), and by Wraith (which has no real name???)
This is a nice little round conversion, and looks very sharp. There has been some debate about how good it actually is, see the Important Posts page for more info.
All photos here are from Brent's Install Page for these. See link below.
