Fairly good point! I'm not sure the Wildcats ever had "official" type designations, and were not simply called by the specialist press to mark the distinction. As a matter of fact, Patrick entered three cars for the 1980 Indy 500, naming them PR-001, PR-002 and PR-003, plus a Wildcat IV according to the Hungness yearbook - I'm not sure the last one isn't a typo. The cars that did eventually appear were the one we are talking about (with but one race on the clock), the even newer car that was evidently the Mk 7, an unraced Phoenix and an old Penske. The Mk 7 was entered for Johncock as #20 ("PR-001") and destroyed in a May 8 accident. The Mk 6 was entered as a backup car #70 ("Wildcat IV", or VI more likely), shaken down by Bagley in his initial runs, readied for Johncock as #20 and then qualified by Bagley, repainted and given #40 for the race. The Phoenix was earmarked for Bagley as #40 ("PR-002"), practiced by him but rejected, practiced as #40T by Smiley and finally qualified and raced as #70. The Penske was Dallenbach's '79 car, and apparently a substitute for backup car #90 ("PR-003", presumably never built or finished), and ran as #40T initially for Bagley, was then qualified by Johncock, repainted and given #20 for the race. Still following?
UPDATE: I checked a few newspapers, and all appear to refer to Wildcat IV as Bagley's 1980 ride, so it's clear the error must've been made on the original entry list, hence the confusion. The following year, all newspapers appear to agree on Wildcat VIII as the '81 car.
