I used one of those for the engine on my 59 Suburban, along with the factory V-8 bellhousing and rear mounts. It worked fine but, I should have just bought the front V-8 mounts and been done with it. If your V-8 does not have holes in the front for the original style mounts, then this is a great alternative.
Got a question, did you have to re-route the brake lines after installing that crossmember? From what I've seen and read, the brackets for that crossmember come close to where the lines run through the frame rails.
