Bits 'O Brickle Ice Cream Pie & Sauce

This is from an advertisement on page 16 of the FAMILY WEEKLY magazine, September 20, 1981 that I just found in one of my late mother's "clipping" boxes.  In case you can't read it, I will retype the recipe below the picture.

Pie:
Prepare 9" graham cracker pie shell
1/2 gal. vanilla ice cream, softened to spoon easily but not melted
One-half 6 oz. bag Bits 'O Brickle

Spoon haf of softened ice cream into prepared pie shell.  Sprinkle 1/2 bag Bits 'O Brickle on top.  Heap with remaining ice cream. Freeze.
Sauce:
1 1/2 cups sugar
1 cup evaporated milk
Remaining 1/2 bag Bits 'O Brickle
1/4 cup butter or margarine
1/4 cup light corn syrup
Dash salt

Combine the sugar, milk, butter or margarine, syrup, and salt.  Bring to a boil over low heat; boil 1 min. Remove from heat and stir in remaining Bits 'O Brickle.  Cool, stirring occasionally.  Chill. To serve: Stir sauce well, then spoon over individual pie wedges.  Serve eight. Remaining sauce may be refrigerated  in a tightly covered container for use as a topping.
