He was out of the Poly-loc mounts for my /6 to B block swap so I opted for the torque strap. It bolted to the motor mount boss and down to the K frame with 2 small holes to drill. Easy to do, rock solid. Inexpensive IMO. Though turnbuckles from the hardware store are like no buck spending by compare and will do a great job.

I also used the torque strap arm on my '73 - 360 - 4spd Cuda. Excellent as well.
