Alston Race Cars video constructor series 1980's

[prhjf]

Does anybody have the Alston Race Cars video constructor series? This was sold in the VHS video format that shows you how to put together their chassis parts? These videos were sold in the early 1980's when Alston Race Cars was in Sacramento Calif. I checked with Chris Alston's Chassis Works and they told me they do not have any of these videos.
