The OS 46 AX should bolt right in. The mount pattern should be close. Another choice would be the TT 46 pro. I believe they also have the same or very close mount pattern. And lastly I believe that the Magnum series would about bolt in. Any of these would be a good choice.

As a side, if you are not concerned about a direct fit replacement I would reccomend the following:

Enya 50 SS, Irvine 45 and 53, Super Tiger GS 45 and 51, Magnum 52 XLS, and MVVS 49. Any of the above would do well in your plane.
