look at 76-87 v6 G bodys /some of the V8 cars had them too--some 76-about 82 Fbodys maybe an Olds/Impala from the same era-- they are out there you just hafta find an older car--- maybe even buy the whole car if you can find a clunker "real cheap" -- even some Isuzu cars had them ---overall usually found in low HP lighter weight vehicles
