Wow, is this a Parts wanted thread or a how to thread? Some good info here but not on a Wanted thread.
That's up to the original poster to do his homework to get the part he needs. He asked for a part for a particular year and model. If you have one, fine. If you don't, commenting on sale and wanted threads is against sale rules.We are trying to get the OP the right part.
Apparently 70 has a sea change of differences that I was not aware of. And that's saying something.
My first model kit as a kid, and I will always love a 70 b. Unfortunately, I never got one.
