Sorry Ethan can't help you and I've got some more bad news. And inquiring at Toyota with regards to my RT40 I was informed that Toyota no longer supports the series 1 (RT4X/RT5X) coronas. I can tell you however that both the clutch and brake masters are the same. In saying that though, they're all old as the hills, and you know 60's spec. Best to take some measurements and see what else from the wrecking yard fits.
Cheers
JA
