I dunno where you are located, but there is a decent sized archery shop in Wabash IN called Bass n Bucks.
Their used bow selection is way down from what it was, but being a Mathews dealer they have a few at times.
(260) 569-1853
IIRC the Switchback and Switchback XT are non adj cams.
You could get either in 65% or 80% letoff, and draw length specific (non adj).
Was about 60 bucks back in the day to swap a cam.
I dunno what the price would be for that old a bow.
Don't know if a new Mission bow would get you something comparable, new w warranty for decent price.
IIRC the IBO spec on a SBXT was 315 FPS.
