Engine Test Stand using K member?

A friend and his son helped me out with this US Cartool replica. I have to say, there was an oversight. I was hoping that this dolly could be something that could have the engine/trans/suspension installed by lowering the body over it but nope. The way the k-frame rests on the dolly is that there are two studs that go through the two front k-frame bolt locations. If the k-frame was supported in a way that did not use the bolt holes it could work.
There's no reason this dolly couldn't be used as a run stand.
