another project- another wiring problem!

yes, spark at coil -- connected and then off, and a gain on, THIS coil ( on this lancer) was starting and running on the 65 dart we worked on other day. I did remove it for another "new" one on hand ( both same brand new) , so is that an indication that particular coil is O K?
new oem type plug wires for slants aren't expensive, I will pick up a set anyway.. I usually like to try to get the project running, before I buy much new parts for them. sometimes I find myself looking for another engine!
yes that was the coil spark wire that is about 10-12 inches.
I did test one plug wire for the heck of it, read like 20-25 ohms, but that wire is maybe 18 inches. thanks again for the help..
the PO( a flipper ) had lived in central mo. last 30 years or more. he thinks this car was used at a local dirt track as pace car. I removed the front seat, for pan work and to get into the dash. plaque glued to dash read: road race participant, Wentzville track, 1976. looks like it had some sort of 2 way radio hooked up,p lace for flag on front fender etc. will look for any ( non factory wiring work)?
thanks again for the input.
