I'm finally down to putting in the driveshaft and it's about an inch too long. The car is a 69 and had no drivetrain except the 12 bolt. I even had to put in the frame mounts. I am running a 454 with solid motor mounts and a B & M Street/Strip TB 400. The driveshaft was supposed to be the right one but you know how that goes. Does anybody have a 69 with a 454/400 setup that can tell me what their driveshaft length is? If I have to order one who do you recommend? Thanks.
