727 Speedo drive gear - long or short?

[OttawaCharger]

G'day
I'm trying to determine if I have the long speedo gear or the short one. I'm going to order a 39T but want to make sure I get the right one. Looks to be about 4.5" long

Long. I went through this a while back.

thank you! Much appreciated.

As a heads up, if you find a short one for cheap, you can easily swap shafts between them.

Please explain this shaft swap to the group.
