I build '40's & '50's trucks. Usually two to three per year.
They usually sell before completion and I enjoy doing it.
I'm always asked how long would the wait be to build a truck for someone and my advice is the same.
Go find the right truck and buy it done.
It never fails to amaze me how impatient or fickle a waiting customer can be during the process.
In this day and age everyone wants it right now. Instant gratification.
I get it. Life is too short to wait on anything.
