Thanks DADS50,
Yes that does help. It looks like your 1950 has shorter spindles which allow you to get a wrench on the wheel cylinder hose end. The tubing is the larger 1/4 inch as well. Your hose is the same one they gave me for the rear. I still don't know what application uses the jam-nut instead of the clip. At this point I guess it doesn't matter as I believe the NAPA hose is the correct one for my truck.
I enjoyed watching your YouTube video.
