Every once in a while a similar thread pops up over on [ur=http://www.chevelles.com]Team Chevelle[/url], and the El Caminos used to land the U2 spy aircraft come up, and some gentleman that claim to be there said they believe they were 427 cars. Try doing a search over on there bulletin board, as this has came up several times over there.

Whether there was such a thing, I don't know...but it would make for one cool tow vehicle!
