Yes the Bridgestone is in the rear and it seems like the indexed movement of the shifter/derailleur isn't enough to make clean shifts either up or down. I've adjusted the cable barrel but couldn't seem to make it happy. I'll double check the freewheel but I know it has Shimano 105 hubs so I'd bet it is a Shimano. I know it could be a freewheel spacing issue but I'm happily running a similar Suntour barcon/derailleur and Shimano cassette on my Expedition and it shifts like a dream. The change to a wider chain on the Bridgestone last night did make a huge improvement. I just didn't know where to find new ones any more.
The Zebra is in the front only and probably relates to a combo of narrow and worn chain and the spacers as John E mentioned.
I'll look for the Bell chain at the big box and give that a try on the Zebra which is a flipper- thanks for the tip on the source. Probably one of the last places I would have thought to look.
BTW it does seem like the Sram PC 870 is the successor for the old PC58 I used to use. That may be an option for the Bridgestone which I plan to keep.
Thanks for the info and help.
