ok guys. and thank you again to everyone for there advice and help thus far.
i did a little hunting and found a fella over here selling a "1967-1978" 904 off of a 318. its on craigslist so i based this off he said it was 60's and according to wiki the 904 was only used behind 318s during that time period.
i sent the guy a message and asked if it was cable link. he wasn't sure. and im afraid i don't know the difference. if i where to have him send a photo should i be able to tell and what am i looking for?
is "cable link" just linkage on the outside of the trans instead of newer electronic trans? im afraid this is a area where im a bit clueless as to terms used.
regardless hes asking 100 bucks. and they seem to be rare around here. i felt that a reasonable deal if it is the correct item.
again any and all help or info appreciated. im learning a lot here thanks for the free education
