Had this dilemma on an older 60that I had and now just rebuilding an 85 60 and here's my 02. cents. On my old rig I pulled the smog stuff becuase I could, Put in an alternator in its place and had an extra battery. Nice being able to jump yourself and....power a winch. Then I replaced the leaky oem PS pump with a saginaw and never looked back. Made my own bracket there are options..There are more saginaw pumps in vehicles then imaginable and its because they are a superior design, simple cheap, easy. Toyota did some things really well...the PS pump was not one of them.
On this build I used a smog pump bracket and mounted the PS down low whare the smog pump would be. Fantastic, open, lots of room and turns smoothly.
