36 tooth speedo pinion for early 70's 727

Problem solved. I ran with mopowers' idea since I had a short 36 from a late, late, model trans and a few spare long shaft gears lying around. Used a 3/8 drive 13/16 socket to support the gear - put the shaft thru the back of the socket so the flat of it supported the gear. Used an awl to drive it out. Broke one green gear and then had a brain fart... heated the next one up with the wife's hair drier. Rather than using a hammer and shocking it out, used the press. Much easier. Thanks all!
