Overall Assessment

Customers found our product high-quality and practical for various car models, specifically on vintage F100 and F1 pickups. A common feature praised was its top-tier workmanship and substantial material quality. Despite some users needing an additional adjustable transmission mount, the tubular crossmember provided excellent usability and was deemed worth buying over making one's own, indicating superior performance among competitors. Its clean look also earned commendations, reinforcing its exceptional value to customers.

I had to order the adjustable transmission mount in order to make this work with my T5 in my '49 F1 pickup. The holes aren't wide enough to bolt directly to the transmission. In hindsight I would have just made my own.
