700r4 question....

[allthrtl]

I'm putting a 90 model 700r4 in my 83, along with a new engine, and have run into a little snag... The 90 model tranny came out of a truck with electronic speedo, so I have to change out the electronic pickup and gear for the old cable system...How do you get the steel signal disc (looks like a gear) off of the output shaft?? It doesn't just tap off like the plastic gear does on the old setup, HELP



Sorry for cross posting, but I'm right in the middle of this....
