OK, Since nobody has offered to help you...
I really do not see anything wrong with your code except your drawing shows 140mm bolt circle and your code gives 138mm diameter.
Please post an example of the code you are getting from MasterCam and a copy of the post file you are trying to modify and I will take a look at it.
If you can, please post a copy of your MasterCam file in V9 format.
I can not promise a quick fix but, I will try.
