I'd like to hear from any TDR member who has the MagView Differential Cover (with lexan window) installed on their CTD. I like the idea of a visual inspection but wonder if the lexan window discolors after long use. I also wonder how the magnets are cleaned off with an oil change. If they can't be cleaned, without removing the cover, then a removable magnet (like the ones in the Mag-Hytec) would seem to be a better option...
