K frame dolly

Would like to borrow, rent or buy a K frame dolly to install a 318 and transmission into a 73 Dart.
Looking for something in the Western NC area. Also eastern Tn.,NW South Carolina or even NE Georgia.
I really don’t want to spend a lot of $ on something that will just set around the shop when done.
If all else fails I will just build one.
Thanks all.
If you build one that dissassembles with set screws then it wont take up space. I like the china freight dolly idea as well. Cheap and easy. Even better when you got a few 20% off coupons. Heres my stalled out k frame dolly project. Center spine will have set screws to hold it in place.
