Rebuild and upgrade the Corvair differential for MORE POWER

Well, as you might remember from the 2021 Corvair Track Classic, I had to retire early when my differential bearings decided they were no longer willing to...bear...anything. So, let's rebuild the diff, replace the bearings, and while we're at it, let's do a custom-machined 4-spider upgrade to radically improve the power handling of the differential. As always, no sponsorships, just calling out good suppliers! 4 Spider upgrade machine work by Regan Metcalf - [email protected] Corvair parts from Clark's Corvair Parts - corvair.com Used parts from Morton's Classic Corvair Parts - [email protected] Music: Endless Night - Karl Casey ‪@WhiteBatAudio‬ Feel The Heat - Karl Casey @White Bat Audio Seeking - Karl Casey @White Bat Audio Follow along on Instagram:   / flawlessplangarage   Index: 00:00 Intro 02:09 Differential Teardown 03:48 4 Spider upgrade 07:18 Drilling and re-threading snapped bolt 11:22 Adding a drain plug 12:54 Differential Nose upgrade 17:34 Setting up the differential 28:35 Reinstallation 32:10 Startup & closeout
