My car is in having the "Riviera Rattle" taken care of. They have dropped the tank as the rattle is coming from the tank inlet/outlet  hitting the trunk floor. I had them pull the sending unit as long as it was off to see if there were any problems. They found the sending unit sock was bad. I see that in another thread Ed found that the TS1000 sock will work for the 1964. Will this same sock work for the 1963? If not, do you know of one that will? Thanks for your help.    Bill
