Yes. It is called GTT (Grand Turismo Transmissions). Most of the parts are interchangeable with a Pantera transaxle. The cases are stronger than Pantera. You can order one with 3.77 or 4.22 (stock for most Panteras) ring and pinion, and stock Pantera gearing or a higher 5th gear .620 or .645 tall gear. The differential is 70% locking (stock was 40%). It is available for Pantera or flipped over for GT40. Here are photos of it setup for GT40.
