If you have drilled and tapped side engine mount holes on the passanger side of the block you could make a bracket that holds a saginaw pump between a piece you bolt into those holes and a piece you bolt to the timing cover and backing plate. That's how their mounted on ford 4 cyls, only its on the passanger side. Look at a ranger in a junk yard sometime and you'll see what I mean. The old old toyota landcruisers mounted it the same way on the driver side.

For the harmonic balancer you've go a couple of choices: find one with more than one pulley, like what came on the bigger trucks.

or, find a two groove 7" or 7 1/4" bolt on pulley from a small block chevy balancer, drill the rivets holding the single pulley on your balancer, tap the holes and bolt the two groove pulley to the engine side of your crank pulley.

I'm sure there are lots of other ideas out there!
