Hi Mando,
I made the filters, stainless sheet drilled to size of trumpet openings, bent up the edges and welded s/s mesh in a semi circle. Glued on special foam rummer used on air compressor filters and other industrial uses.
The dissy drive is a standard Ford item, off Explorer I think used to connect with coil drivers and coil packs.
As you do not have a PCV valve you will need to vent both rocker covers to the catch can. As leeroy experienced mine is fine on the road but at high revs at the trak there is considerable pressure and associated
oil. You need to run large (dash 1o 12) hoses to the catch can.
Cheers
