Low dollar torque strap

My 360 is quite mild, 350hp/400tq, maybe. The mounts I'm using are some I had left over from when I was setting up the car, but they don't look old. I do know that I would be leary of using the poly locks with my setup but in your case they seem to be the perfect choice.

I forgot the brand but I got the mounts from Oreilly.
