Hello Vance,

Awesome job on building your trailer! I am happy to find the right spring for you, but in order to do I am going to need quite a few measurements. I have included a picture of what measurements I need, can you please respond back with the measurement for each letter?

@VanceF Vance, I wanted to let you know that I am still waiting on a response from M-3, she believes that it is going to be a custom order job but is waiting to talk to the owner about it. I will let you know as soon as I find out.
