Early front pulleys/ps pump. Onto 1970+ 360. What needs changed?

Good Afternoon all,

Hoping you can help me, help help a customer.

Customer has all stock bracketry off a 1968 318. from his running/driving barracuda.
it had the early driver side dump water pump.
i have confirmed it has a saginaw PS pump, not a federal.

He has bought my 408, which for this discussion, is a LA360, with LA timing cover, and LA alum water pump with passenger side exit WP.

His "early" ps bracket will not work. (my oversight)

I found this bracket for a saginaw pump, and for the passenger side alum WP he has on the engine.

my concern, is if i get him this bracket, his original pulleys will not line up, and we'll just chase our tails forever.

Anyone done this, have any wisdom for me? As simple as buying this bracket, or no...

thanks all.
