I'm going to be changing rears in my 76 Cutlass soon. Going from 2.41 to 3.73. The speedo will be off, I know. I'll get the right gears for it (speedometer) as I go on with the whole project. But in the meantime, to test drive the car, can I just disconnect it from the tranny, tie it out of the way and plug the hole for now? Is there a recommended way to seal the hole? Certain "Plug" that anyone had luck with? If I leave it connected I'm afraid I might "Pin the speedo" and break something because of the major difference in rear gears. Thanks. Tom
