Is it a vibration or a shimmy (shake, whatever). All three of my K's at one time had worn leaf spring bushings, and it would cause it to shake at a certain speed. The '69 was so bad that it would knock things off the dash. The '68 does it a tiny bit at 45 and if I hadn't had the problem with the '69 then I'd probably think it was a vibration too. The burb has a very small one, but it's getting all the front/rear bushings, tie rod ends, etc replaced come tax return time.
