crashoverride, Actually that's a error on that website. By looking at pictures in my collection and in the gallery on this site, the Frontier Lift had a box type cable cars similar to what the Sky Ride uses. The link you gave show, I belive, cars that are from Dorney Park and I belive rumor was it that those were supposed to go into Camp Snoopy(Someone please correct me if I am wrong).
If you want the some nice pictures, visit the gallery section on this site. There are several history pictures from members of this site there.
Also I belive if you do a search, a few months back someone actually used some aerial shots of the park and drew lines where the Frontier Lift would be.
