Take a look at the right front wheel on this D200. It appears to
be a one piece 16" with the correct hub rim for the stock "male"
3/4 ton pre '69 dog dish caps. I can't tell whether it is a one
piece tube style wheel, as it looks like the valve stem is coming from a large
hole which would indicate an inner tube. I don't know if this is a
stock Sweptline wheel or something earlier. I had one of these years
ago but it was too rusted up to use. All the other 16" stock '68 and
earlier vintage wheels I've seen are split ring. If you're looking for
a set of one piece 16" wheels and you're not particular on this exact
style, you can use any Dodge steel wheel right up through '92 or '93.
They'll take the "female" style dog dish cap that the '69 and later
Sweptlines came with.
