Pertaining to the spring removal, looked pretty scary. Sometimes wrapping a safety chain thru them, gives you a little more piece of mind. Just in case something slips, if ya know what I mean. Congrats getting them out, with all your teeth. Usually, when you're lowering the jack handle, you're not too far away from the action.
The frame will be nice, once it's all cleaned up. Have fun, cleaning and painting. Will like to see the process used during installation, how you square it up.
