Do or DONT fiberglass body parts

IMHO

You're pushing 80, why do anything to the car now. Get an assist on the clutch or have an automatic swapped in and enjoy the car.

Perhaps enlist a friend or family member to be the driver

Or better yet find a kid in the neighborhood and take him or her under your wing and teach the things not tought today. Then will the car to the kid.

A lot of good memories can be had.
