Searching threads here revealed this TSB.
One thread said it applied only to L series: 62L11289-62L11307, 62L12581-62L12801, 62L51104-62L51140
Not sure if this is correct or what L series means. Are these Chassis or Engine number for Model year 1978/79?
My 1974 Chassis #9114400346 Engine #6341983 has something there as pictured but I don't know if it leaks.
Thanks for any replies.
