does anyone know what a 69 396 jack base looks like. the reason I ask is on my april 350 ss car i have a sort of oval base with well rounded corners with u-69 stamped in it. I also have a 70 z with a little bit larger base and sharper corners with nothing stamped on it. now to the point of my question: i have an oct 69 396 car and the base is exactly like the one in my 70 z however there is a u stamped in it. no 69 just a "u". does anyone know if this is the original base or not. I have heard that maybe the base on that late of a car should look like the 70 with no stamping at all. confused???????? thanks in advance
