I know the front cover plate whole is 16MM and the Rear is 18MM, But does anyone know the thread pitch on the holes? I know RB and Mazdatrix have adapters from the metric holes to AN fittings but they dont match the red and blue scheme on the lines.

I believe it's just 16mm x 1.5 and 18mm x 1.5. for the -10AN size.

Yeah, but believe me, they are cheaper!!!!!! I did the SS oil cooler lines myself, but I bought the adapters and the washers from Mazdatrix. There is only 1 that you will ever see anyway and that is the one on the front cover. If you want a pic of mine I can email ya one.... It doesn't look bad, actually it looks cool with the goldish adapter and the red and blue 10-an fitting on it!! I got everything else from summit. I think the total was 135 for the hose and all the fittings. (get two 3ft sections of summit 10-an SS hose, its much cheaper)

 

Thanks to both of you.
