I have a quick disconnect, but it is not a Grant. I have not priced the Grant parts. All of them are easy to install. The only thing you may rn into is the extra "height" of the quick release.
I used an NRG short adapter and a close quick release adapter (not NRG). I also had to use a 10mm spacer/adapter to fix a clearance issue between the adapters. The parts I used required that I have a wheel with a MOMO or Nardi bolt pattern (both 6 bolt, but different). If you use both parts from NRG, they will probably work together and not need the spacer. With all this happening, I had to use a "no-dish" wheel to get the proper distance from the turn signal stalk. If I am correct, Grant does not make a "no-dish" wheel.
If you do not mind reaching a little far for your turn signal The grant wheel/quick disconnect will work. I personally like the selection of 6 bolt wheels better than the Grants. The Grant base adapter requires that you remove the clockspring retainer tabs at the top inside of the column bezel. I used a dremel and a sanding drum with a lot of care.
If you get a wheel without a horn, the Grant horns can be fit with the addition of a large "washer" to cover the gap between the Nardi/MOMO center hole. I made one with a piece of black plastic from a dash support. It is about 1/8 inch thick.
