Welcome!
Gotta love those Yellow MK-IIIs.
Mine is Yellow with White stripes (with black pinstripes).
Definitely nut and bolt the car...especially the lower/outer pivot bolts on the rear suspension. Ask me how I know what can happen when they come loose and break. :/
Mine is also titled as a 1965 Ford. Previously titled in Cali as such, so the actual process was cake and took about 20 minutes total, and I walked out with plates. I went to the Hillsboro DMV, which is actually pretty good.
Looking forward to meeting up someday....
