smallblock flexplate

get a hold of these cats. http://www.areds.com/ i have known them since the late 60s. 90% of ALL trans shops get there parts from them. they can answer any Q

Thanks moe, will checked them out. Got a little more info from this friend of mine. He said the flexplate came out of his 68 dart that had a 360 transplanted into it. When he pulled the 360 out to do some restoration work ect. He is putting in a steel crank 340 and reusing his neutral balance conv and will not use this flexplate. The trans is a 904 as he states. He bought the car with the drivetrain installed so maybe the previous owner used this flexplate without knowing what it was for. I rode in this car and never noticed any type of vibration, but don't want to take the chance of using it if it's not for a 360. So my next question is what is the difference from a 904 to a 727 when it comes to flexplates ?
