JDM_DOHC_SiR. Well if you yourself have tried drilling droop screw holes into the short A arms and that they work then I would go out and get them. If it's just a hypothetical guess that the short A arms may be able to accomodate the droop screws then I would't spend all that kind of money.
I haven't tried it ..."YET"
But I will soon....
..there is space to put droop screws with the Pal arm conversion
