With that style of housing you have to have the correct housing for the tooth count of the driven gear. It also has to be clocked correctly in the hole. Meaning turned so the tabs on the hold down clip are on the notches on the housing. That orients the housing so the gear properly meshes with the drive gear.

I've never had any real trouble getting the end of the cable to go in the driven gear but have had to turn more than one to get it lined up. usually you can do that at the bottom when you are trying to line them up. You just turn it a minute amount and gently go again.

Make sure that the cable is routed smoothly from the trans to the speedometer. Sometimes we try to get it in too tight of a bend and it wants to bind up. I've seen that both in cables that were too long and ones that were too short.

The speedo gear box I have is located in the photo. You'll see where the cable is disconnected. Guyryan, the part that flexes is on the trans side of that big nut behind the small bolt. I think it's the speedo housing just moving in the hole of the trans cover.
