If I'm reading it correctly 1970 350's and 455's used the same flex-plate on th350's or th400's. What about swapping to a 200r4? Is that a different flexplate or will the one I have work?

Thanks for the help,
Tim

I'm pretty sure the Jetaway, TH350 and TH400 torque converters will all bolt to the same flexplate. The 200-4R torque converter uses the same bolt holes as the Jetaway (for sure, just did this myself).

With the exception of those used on the 1980s FWD applications (in front of the TH325 and 325-4L transmissions) motors, ALL Olds flexplates from 1968-1990 will interchange. All have both bolt patterns for the converter also.
