The MPE IC7SB is the same style coil the Echlin IC-7 will be and is essentially the same coil except MPE is Napa's lower cost brand. Echlin is their premium brand and usually has a better construction and warranty along with a higher cost.
For either coil, when trying out or using in place of the stock Autolite or Delco firewall mounted coil you will need to provide some kind of mount. Back in the 50s this was a common issue when replacing coils and there were aftermarket brackets made to adapt the more conventional or modern style coils to the firewall mounting locations. One of those is shown below and they frequently appear on ebay. For just doing a temporary test you could buy a single screw inexpensive coil bracket that goes around the middle of the case or even tie wrap it securely to something.
If you do find the new coil solves the problem then you can look for a bracket or perhaps your mechanic can make something. I am using an IC-7 in my 47 and made a bracket to more or less match the original arrangement with the inside terminal and armored cable connection so everything looks almost stock. The bracket I made is shown below the aftermarket bracket.
Something to note with the ebay aftermarket firewall bracket is they did not bother to provide a proper way to run the wire thru so you are still on your own for that. If you find the coil is an issue and want to try and find an aftermarket bracket for a permanent mount strongly suggest you do not do what others have done and try to run the wire thru the small slot. A few miles of vibration or an accidental pull on the wire and that is almost a guaranteed short waiting to happen.
Once you have run the wire that is currently going to the terminal on the base of the stock coil out of the passenger compt and into the engine compt, if the car battery is still connected in the stock Positive ground configuration the wire from inside would connect to the NEG terminal on the new coil. The distributor and OD cutout wire would connect to the POS terminal.
