I think the 13/4" breather bolts may work. I'll pull the A/C cover tonight and check. might have to modify the filter though

I am 100% stock. Looking for ways to get this done on mine.

I used the longer Kury bolts (1 3/4" I believe), you can get them at J&P, same brand and part numbers a buck cheaper.

If you have a ventilator like you said in the 1st post those bolts are useless. Unless you plan to drill holes in your back plate to run hoses.
Just buy the fittings, tap and hoses and be done.

The filters really only help if you are doing a short run and it's exposed to air flow (like below the intake). If you are running a line down to the underside of the frame it's not a major requirement. Remember, this is crank pressure running through a 1/4" ID hose. In order for wind to actually push that pressure back into the engine, the line would need to be mounted facing directly into the wind and a much larger orifice. The filter that they recommend using under the intake gives it more surface area and helps break up air flow to keep the pressure down. So it's half dozen of one, 6 of another depending upon how you set it up. My problem before was I forgot basic physics and mounted the damn thing out in the open where even the filter wouldn't do much good. Didn't affect the crank pressure, just tended to draw more moisture than it should have.
