Thought you guys would enjoy this. This uses Lonnie's little known 200-to-4L60e flange bellhousing adapter and the nailheadbuick.com bellhousing to create a proper fitting overdrive for cars like the 65-66 grand sport and early rivieras etc. previously you had to use hokey ass adapters (which are $700+ and require floor/driveshaft mods) or a 4L60e (which requires a controller and driveshaft mods). Test fit/mockup was done this weekend and it fits the engine perfect. Will be doing a full write up as we go with everything that does/doesn't work, probably on 65gs.com or v8buick.
