I run them on my setup SD. Strange and Moser said they didn't have them for the S197. When I saw Moser had a 9" for the S197, I called Shane at Moser and started asking questions. I got the 9" housing ends used for their S197 specific 9". Had it jigged up. While I was at it, I put in 35 spline gun drilled fluted axles and welded up the housing. The S197 specific housing ends will allow you to use the stock calipers, keep the E brake as well as the ABS....if you're still keeping it. Honestly, the rear brake calipers is the only thing I haven't changed out. I've been reluctant to tackle that one due to fitment speculation with the Bogarts. There may be an easy solution now, but there wasn't a year ago.
