So I’m working on getting the right drive/driven gears for the T5 I have in my 68 and 69 Cougar- similar builds and both have a 3.89 rear gear. But until I do I’ve seen these “HUD”s come up for sale on Facebook Marketplace. I checked on Ebay for kicks, and there are a LOT of options. Has anyone here used one, as an interim solution? Actual mileage on my cars is moot, as they are either over 100K, or just will be sold with a mileage known inaccurate statement.
