Mike,
1) I’ve never heard of anybody having this problem EXCEPT for one guy that actually had a bad speedo. Would you like to borrow a spare speedo to confirm that your cable problem is actually a cable problem?
2) Who throws away Pantera parts??? Even ‘bad’ parts have value, for reference if nothing else.
3) I also have NOS Ford speedo inner cable available if you think your vendor sheath is good but cable is too short?
4) Personally I suspect your issue with Vendor A cable is just down to routing.....
Let me know.....
