just sent Fred a PM today....hopefully get the aluminum rear brkt from him. Hoping he finds a front also but if not I am that much closer!:Brow:
You are correct. Folded over tab Part number on front steel bracket is 1238314 Also stamped 455-A-350 Great picture of what I need here: http://www.v8buick.com/showthread.php?t=182213&highlight=ps+pump+bracket+AIR
Not sure how much help it is but it's at least a last ditch option. The pump is blown but I'm pretty sure you already have a working one anyway. http://cgi.ebay.com/ebaymotors/1973...r_Truck_Parts_Accessories&hash=item3f0e80210b
There's a chance I have the power steering brackets. It looks like you found a choke, but I do have a few extra NOS ones of those laying around here. Also if interested, I have repro choke thermostat gaskets available.
