I have both DYS discs and will happily help out with the mono. You need the earlier Image disc for the last line, and the new BD or some other source for the correct uncut flashback cue.

TFC is one of my big mono wishes, and I've never been able to find it. (like Bullitt) The LDs are stereoized, and the new remastered BD includes a "mono" track but I haven't gotten to sample it yet. The one LD I've wanted to check is the I and II double feature but I've never been able to confirm the track is indeed mono.
