Grant 4313 vs Pilot SW-900 install kit - Blinker cancel?

I bought a nice wood Grant steering wheel from Pep Boys with their 35% off deal last week and though they had a bunch of Grant install kits, they did not have the 4313 kit. Instead they had a kit from Pilot (kit SW-900) which lists as the right kit for Chrysler 68-72 Std. Col. Chrysler models and compatible with Grant wheels. It's basically a Grant kit, same hub style and all components match. However, the back of the hub has a couple of grooves in the collar around the threaded steering shaft channel, but these do not cancel the blinker. I think I have seen a Grant hub with a nub that projects out from the collar that would perform the cancel, but can't seem to find it. Grant's site does not show the back of the hub in 4313 kit. Can anyone confirm that the hub in the Grant 4313 kit does have the signal cancel provision?

Here's what I'm working on:

Yes, I know. I'm going to get rid of that awful shift light from the PO (doesn't appear to be hooked up anyway) and move the fuel gauge up there if I can ever get it working. For the curious, as I've received questions before, the horn button was on the old Grant wheel that came in the car. Can't seem to find that anywhere, so pulled it off the old wheel for use on the new. That install was incorrect too - no horn connections, wrong hub, etc., so can't just reuse the kit that was in at time of purchase.
