I'm stumped...help with K-Frame stand/dolly

I tried everything.....I searched the internet for hours....

I have the US Car Tools K-Frame engine and transmission stand/dolly and the Alterkation square tubular K-Frame. Also have the adapters from US Car Tools for the Alterkation suspension.

I'm trying to get the suspension on the dolly to drop it out.

For the life of me I don't understand how it attaches. The adapters are VERY loose fitting to the K-Frame.

I just don't get it.....here's some pictures.

Adapter...







Front support...don't understand it's use...!



See how much of a gap there is....I doubt it's "wrong", I just don't get it...



Anybody ever done or have a picture or anything?
