It is applicable to cessna 150 serial numbers 17801 to 15064532 and possibly higher numbers that are not in the 1959-1969 parts catalog.
CORRECTION: Gordon just emailed me and said that he had the serial numbers wrong. It Should read
Serial Number 17001 to Serial Number 15064532.
No harm no foul <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> Still looks like a good deal if anyone is interested.
