Teleflex NFB - Steering Wheel Hub Bushing (Adapter) Question

[oarwardbound]

I have a 1974 Invader and I am installing a new 17' Teleflex NFB SS151 Rack and Helm. I was ready to install the original steering wheel when I realized I had a problem. The inner diameter of the original steering wheel won't meet up with the new helm key. I contacted the manufacturer about adapter options and he told me there are 2 bushings to choose from, HB0572 and HB0573.

I have no idea which one I should be getting. The inner diameter of the inside of the steering wheel is 1 inch and the diameter of the shaft is 1/2 an inch, or 3/4 of an inch with the key in place. The inner diameter of the steering wheel also seems to be tapered slightly.

Pictures below.

Ayuh,... Welcome Aboard,... Unfortunately, there ain't no adapters for that antique wheel,...

The part #s ya got are to go from the 3/4" tapered to 1" straight, or 1" tapered....

The helm for that wheel ain't been used since the '60s....
It actually was a Square drive, not so much tapered...

Thanks for the quick response Bond-o.

Is there any particular wheel I should be looking to buy for that SS151 system, or will just about any wheel do as long as I stick to the specifications required?
