Does anyone know if/where I can find a stock, non SFI 184T flywheel? I'm trying to mate the 428 in my truck to a NP435 for daily driving applications without spending a fortune in performance parts that I won't need. All the SFI approved 428 flywheels I have found come with this warning: "Performance and SFI-approved flywheels must be used with performance clutch discs only. Use of a stock-style clutch disk with a performance flywheel will often result in insufficient operating clearance between the disc hub and flywheel bolts."
