18 Spline 10" Clutch Question

I guess my first recommendation would be to go with the larger flywheel, bellhousing and associated items but if you really don't want to do that check with American Powertrain for a clutch. I was at a car show in Houston and a guy had a 64 Dart with a 340 and he had the small bellhousing. He claimed he had converted from a 3spd to 4spd because a friend gave him a tranny from a wrecked Roadrunner. After he was fairly well underway with the project he realized the tranny was 18 spline. He said he hunted all around and finally found a clutch at American Powertrain. I asked him how it was holding up and he said he was having no issues and it didn't take a bionic left leg either!
