Yup! I think my '77 Chevy Nova I had as kid had one of those bumper jacks. I mean, back then that big chromed steel bumper was attached to an actual frame and we didn't think of them as bumpers but battering rams! That Nova could plow through anything and come out unscathed. Ahh.. The joy of working on a simple straight-6 250 with so much room under the hood I could almost sleep in there and close the hood over me.
