You'll find differing opinions on this, but I ran a 12v system with a 12v coil for years with two resistors, the ceramic one and the coiled wire version, in series. And it cranked and ran fine and points lasted several years. Last year, I converted further to Electronic Ignition, and I'm pleased with that, too (but I saved my points plate just in case!). Mine is a 48 8N. I don't think you're risking much either way, but I would use the resistor you bought, and I expect it'll run fine.

As long as your new coil is a true 12V coil marked "12V No External Resistor Required" you'll be OK. A lot of supposed 12V coils are actually 6V coils and there is a high resistance wire in the vehicle's electrical system to compensate.
