1972 Scamp in New Zealand

Ok guys I need some recommendations, I need to get rear 1/4s ordered and sent to New Zealand, where’s the best place to get them from, I can’t seem to find Scamp ones, only dart rear 1/4s but there is 70-71 or 72-76, what do I get?

also it turns out that my K-frame is tweaked, has anyone got a factory one for sale that they would be willing to ship to my freight guy in the US? At my expense obviously haha.
