Mine is an "84 with a weakening cockpit pedestal. The base is corroding, mainly at one quarter of the rim, but proceeding toward the pipe-stand in such fashion that if it continues for a year or two(?) it could get us it serious trouble. (It moves only a little at the wheel, under a good bit of a push.) I'ver been looking unsuccessfully for a replacement base, and may have to resort (ugh) to manufacturing one myself. Any experience or advice with this problem out there??
