I've been hunting down a 8.5 10 bolt to swap into my '68, and finally found one after over 8 months of searching! I'm all for swapping in OEM parts, instead of custom ordering something, both for the ease of headaches when tracking down a shop for the project, as well as the lighter load on the wallet! I know a lot of people will say it's best to upgrade the driveshaft anyway, but it's always easier to sit behind a computer screen and spend other people's money. haha
How did you find that your pinion yoke was worn? Was there a vibration after installation? The rear end I got spent a number of years outside, so the tubes are pitted, and then a number of years in a shed. All in all, it probably hasn't seen use in around 15 or so years, doubt it'd be a smart idea to simply flush and fill the fluid, and throw it in my car!
