This solution is not for everyone who wants a showroom stock car...........
It's only for people wanting to make a car faster to work on....

On some cars, if you remove the plastic panel, back where the
wipers plug in, there is a trough under the plastic where water drains out at the edges.
With some cars the firewall can be cut; above the bottom of the trough,
and cut slightly wider than the alternator, and an aluminum inspection
cover made to cover it, once the alternator is replaced.
The time spent making the opening and cover will SAVE a person time later on
every time they have to get that alt out, or need some
extra room to work.........-Bob
