Will this Tuff Wheel adapter work ?

Considering putting a Grant Classic Nostalgia Tuff Wheel on the 68 Barracuda.
I have read several posts here at FABO that the Grant adapter part number 4313 will put the steering wheel too close to the dash and the best fit is with using an OE style Tuff Wheel adapter. Will this aftermarket one work on my 68 Barracuda with the Grant #846 Tuff Wheel?

I noticed that it says '70 and up, is that because 1970 is when the Tuff Wheel became available?
I will also put a post up in the wanted section is case someone has an OE adapter they will part with.
