OK, so of all the possible places to post, this is probably the least relevant, but oh well. While I'm At It(tm) I'm adding power steering to my 67' NADA project. I've procured a p38a steering box and reservoir, fabricated and welded in a reinforcing bracket for the frame, and scraped most of the gunk off the PS pump from my 300tdi. Now, theoretically, I just need some hoses. I'd like to put AN adapters on everything, so I can make custom hoses to fit (and probably add a cooler inline somewhere). My little thread gauge thing seems to think it's 5/8 NPT on the high pressure side, but everything else on that engine is metric, so suddenly finding a fractional thread makes me v. suspicious. Does anybody know of the top of their head what the PS fitting sizes are for the 300tdi / p38a?
