mostly in the dart light's and the feather dusters (for the A-body short case) but they were in anything that had a 4 speed option (pickups, vans) Also I think the f body cases were short but it has been awile sine iv seen an f body with a 4 speed. And I dont really belive it but star parts also lists them for early jeep cherokee's and wranglers. but iv never seen them with one, just the t-4,t-5,& the asian warner's
