Those shrouds I have are '70 up probably /6. Should be fairly easy to find in the state of paradise by the sea.
The question is how that might fit or be fitted on an early A and whatever radiator is being used.
Here's intact one laying on a '68 radiator with a '70 bottom tank.
Why are you changing water pumps?
The Edlebrock pumps are like that. They supplied fittings, but they were brass fitting for the aluminumn pump. :realcrazy:\
Bigger problem was the pump needs to be ground back a bit to fit. Told 'em - sent 'em picks. Bet they never fixed the issue.
