can anyone recommend a helm that will accept the original magnum wheel. It is a 3 bolt pattern and center nut as opposed to the new style that has 6 bolts and center nut for mounting.

you need to find an adaptor. here is a link to one possible source. I'm sure there are others.
Go to Grant steering or MOMO they may have sources.

The original Teleflex is still available. I have made mine fit with a new hydraulic steering set up from Imco.
