speedometer -transmission adapter-extender assistance

After changing the M-818's transfer case from the Rockwell T-138 to the Rockwell T-1138, the speedo cable is not quite aligned. Can y'all look at this picture and tell me what I have here?

It appears there is an extension on the t-case going to the speedo adapter. As can be seen, it is a little too short, trying to kink the cable.

What is this extender from, and can I stack them or get a longer one?

At least it has a grease zerk! How long is the speedo cable? would a longer one help? Maybe you could turn the adapter CCW so it runs next to the T-case, instead of around it?

I didn't know the 5 ton adapters had grease zerks.

Some deuce ones do too.

yes, but see how the cable is kinked? It is not long enough to reach all the way to the t-case, I need to extend something here so it is not forced against the t-case like that.

That is to say it is not long enough to reroute.

I got to say I was at first concerned about the new t-case being a little off-center and the shortie driveshaft ftom the trans to the case therefore being at an angle, but there has been no issue at all, whatsoever, the shaft and joints run no warmer than the others, and I have put 1000+ highway miles on this thing at 55-66MPH. I need to change the front tires to speed rated steer tires because they run warmer at 65 than at 50 where the truck is supposed to be. They are not hot but still it is a safety issue, and I am sure all those who generally give safety advice would agree that semi tractor steer tires are the appropriate items for the front when the truck is run over 55. The rears have remained cool as have all the hubs and the rest. .

I would go to a speedometer shop, just have them make a cable extension

That is a great idea. I don't know why I didn't think of it. Too direct I guess! I have to anyway change the adapter due to the 0.73 overdrive.
