Working on mounting a C4 Z51 power steering cooler on the front end of my '56 (with C4 front end). Had to make the brackets for it myself since I couldn't find the factory ones to save my life. Picked up a stock '89 Z51 aluminum cooler from ebay...these things are monsters...10 pass coolers. GM wasn't screwing around with these things...it's massive. Mocked up the brackets with cardboard, have the brackets cut...need to bend them a bit in a vice as GM had them mounted at about a 30 degree angle (I think for ground clearance). Will get them on this weekend and take my pops for a ride and scare the crap outta him
