The ad is slightly incorrect, the chassis was built in house by John Evans and was used as an EPA test mule. The chassis bears no resemblance to the Kudzu IMSA Lights chassis, and John Evans never worked for Jim Downing at all. Evans simply purchased a used DG1 Kudzu body for this test mule, thus inheriting the "Kudzu" designation, despite have no mechanical relation.
Nevertheless, it's a neat piece that could probably be pretty fast in the right trim.
The Jim Downing DG-1.
As noted, the bodywork came directly from this model of IMSA Lights.
