Motor Mounts 1970 (1971 Engine)

[70LemansSportConv]

Need to replace motor mounts on 1970 Pontiac Lemans Sport Convertible.
Engine is a 1971 455. Driver side is failing.
Looking for something a little stronger to handle the torque.
Would the Mity Mounts listed in Ames (N242B) be a good route? Other suggestions?

Thanks!
