'69 225 into a Valiant with a 170

I can't seem to find a flywheel that will work, and I'm a little confused about which oil pan and pickup I would need to source.

Same oil pan and pickup. 1968 and up flywheel. Real easy. I have one, but one is all I have (I think) and if it is, I ain't gettin rid of it. I may possibly have anothurn. If I do, I'll let you know here d'rectly.
