Yesterday my father-in-law and I built a K-member dolly. I used a small wooden cart to install the Challenger engine but it wasn't very stable. The engine wanted to tip side to side. I wanted something that would be solid that I could store an engine/suspension on long term. We started with a crude stand my dad and I had built years ago for the Challenger. The original stand didn't have any wheels on it and used the sway bar mount to attach the K. It did the job but I wanted something nicer this time around.

I used the outer frame mounting holes to attach the K to the dolly so it would be stable. The four arms that support the K are attached to the bottom of the main "T" so they can be unbolted and removed during installation. I didn't want to guess when making the trans support so I'll add that once the engine/trans are on the dolly.

There are better designs out there but this one didn't cost me anything and should do the job.
