Help. 8ba in ‘46 Merc

[Aarongriffey]

The last time I did this was in 1955. Don’t remember much about it.
This engine has EAB heads and narrow belts. Also has car water pumps. No bell housing.
Will the 46 Merc water pumps fit on the 8ba?
Can I use the 46 Merc generator and fan on the 8ba and use all wide belts.?
Should I get a pair of narrow belt truck water pumps? Is there such a thing?
Should I get narrow belt Merc water pumps?
Will a ‘52 truck bell housing do the job. Will the starter be in the right place?
Thanks for any help and advice.
