Done.
And then I notice http://www.imcdb.org/vehicle_631534-Chevrolet-Step-Van-7-P-10-PS10535-1970.html
If P-10 is an a.k.a. name and not following Step-Van in the formal name, I think it is better to list it with P-10 as chassis code like we did for others.
Also, I'm not sure it is really relevant to include the "7" in the name, if that's just for the length.
