Which style pump?

Stock type Saginaw ?

Or GM Type II pump ? I don’t think anyone makes brackets for an LA small block. Be ready to fabricate your own here.

There are multiple pulley and bracket setups for LA:

Cast Iron water pump:
Saginaw
TRW (round neck) -I think all cast iron water pump with A/C got this pump

Aluminum water pump
Saginaw -starting 70’s A/C had Saginaw pumps. May be multiple bracket setups from 70-89
TRW (round neck)
