Take the water pump and spacer off and put on your pre-smog water pump.
You'll need to get appropriate metric studs or bolts to hold it on as
your old bolts are SAE. You'll also need to swap the crankshaft
pulley.
You may have longer timing cover bolts and spacers. Again you'll need
appropriate length metric bolts.
Your pre-smog distributor will drop right in.
The brake master cylinder is an entirely different issue. The stock
late master cylinder won't fit as it will not clear the air filter.
The conversions I've seen were with different engines so the clearance
was different. Additionally, you would need to add the pressure switch
and make many new hoses.
