68 small block water pump and power steering??

Ok I am making the swap on my dart from the orginal 273 with power steering to my 340. I want to maintain my power steering . looks like we have to completely differant water pumps. The old one is a driver side bottom out and has ears on it to accomadate the PS pump? is there a work around on this or do I just need an old style water pump?? im going to check at checker or pep boys tomorrow to see if the have the old style pump if so Im good to go other than the radiator is in pretty sad shape.

Let me know if anyone had dealt with this before.

thanks Chad
