On the UID side of things, it looks like I saved at least this one (there may be more):
The Doe Network: Hot Case 542 /
NamUs UP #7648
Unidentified White Male
The victim was discovered on September 14, 1974 in Laguna Hills, Orange County, California
[Note: Coroner site says roadside area 0.3 miles south of Calle Corta and 0.4 miles west of El Toro Road]

http://egov.ocgov.com/ocgov/Sheriff...roner/Unidentified Dead/John DOES/74-03389-GR (currently no postmortem photo/sketch; fingerprint and dentals scanned)
From the NamUs entry:
"Nude male found along roadside in El Toro. Valium and ethanol intoxication."
Until at least 2008 this UID's cause of death was listed on the Orange County Sheriff's Department site as HOMICIDE. The Orange County Sheriff-Coroner link above now lists the cause of death as ACCIDENT, I assume due to the Valium-ethanol intoxication. (Doe Network still lists it as homicide.)
However, although combining Valium and alcohol recreationally would not have been uncommon, Randy Kraft is known to have drugged some of his other victims with the same combination.
Prior to the UID's death on or around September 11, 1974, the most recent known Randy Kraft victim would have been Gary Wayne Cordova ("BIG SUR", found August 12, 1974). From
truTV.com Crime Library: Randy Kraft (emphasis mine),
Edited to add: A quick runthrough of NamUs, Doe Network, Charley Project, and the California DOJ missing persons search site did not turn up much with regards to realistic MP matches.
