Also not pictured is a sort of cradle that a previous owner installed on the floor to mount a cd player without modifying the dash.
Is the clicking noise possible coming from your hubcap? I have a noisy hubcap on my 68, right now.
A bad universal joint in the driveshaft will give you a clicking sound also. Your car doesn't have a CV joint in the front wheels, however, it does have a type of a CV joint that joins the 2 halves of the driveshaft together, however, I doubt that you are getting any noise from it.
Blake... You really need to get a 1968 Factory Service Manual and start learning more about your car, if you are to become educated in its repair. Otherwise, you are going to be at the mercy of whomever you take the car to for service, and without having more knowledge, you are bound to be taken advantage of. Having the knowledge that the FSM can give you will more than likely save you the cost of the FSM on your very first repair.
