5-speed swap! I’ve been gathering parts, and doing research for quite a few years and I decided it’s time to pull a trigger and get it done. Car is a 72 Duster 340 clone. It’s got a pretty healthy 340 backed with a 4-speed & 3.91 gears. I love the 3.91’s but not at highway speed! I picked up a new in the box Tremec 3550 5-speed many years ago. A few years ago I picked up a Lakewood conversion bellhousing. A 18 spline Hemi throw out bearing fits the Tremec perfectly. A Magnum pilot bearing machined out to press in a Mustang T5 pilot bearing. Along with a Mustang 10.5” clutch disc. And a Hurst patch panel to cover up the floor surgery. I just got started today and will update as I go.
