A little like the "plastic" headlight gear? The brass fix works for me.

LESS than a dollar ? CLUELESS... changing the color of plastic parts for 7 pieces cost 7 cents, or 49 cents a copy. to say the cost of metal vs. plastic would less than a dollar is simply wrong. Cost of a small plastic latch( cost to manufacture ) is ten cents, ( because in most cases it's injection molded where 16 can be made in a 30 second cycle. the cost to manufacture it in metal ( requires machine time, and process time and finish time and then a protective coating, chrome, or another corrosive protectant.. cost to manufacture a single metal latch is 1500% more.. plastic part=10 cents
metal part 1.50
Adding metal would have added several hundred pounds and over 1000 dollars and way out of the designed budget. Intake manifold ( glass filled Nylon, sand cast molded cost to manufacture 18 dollars and 50 % lighter than aluminum. "1 plastic item" cost savings 15 dollars and 15 lbs lighter. This is the reality...
Radiator with plastic expansion chambers. 5 % lighter than all metal, and 5 % cheaper to manufacture.
But then " JUST FOR THE CLUELSS "... plastic was the only choice because if its specific gravity... The whole idea in the process of building a car like the C5 and have it pass the gas guzzler tax threshold was the most aggressive focus in design ( Every push from Dave was to make it lighter") again for the clueless who spout things like it would have only cost GM a dollar to go from plastic to metal.. is just pathetic...This is the reason why I always say.. "Be Very careful who you listen too here"..
People who know nothing about automotive design or manufacturing should not open their mouth about things they know nothing about.

For the most part, the CF community remains a friendly place where ideas, thoughts, and assistance can be found. Unfortunately, there are times when members forget that this is an Internet forum and issues between members can get out of hand. This includes members turning to the forum to air a personal offline/on-line problem which results in sides being drawn by participating members.
In these situations, it is the forum's role to expeditiously end any conflict for the good of the forum and its membership. The forum's goal is not only to remain family, work, and corporate server safe, it also will not serve as a battleground where offline/on-line personal matters and drama are permitted to be played out in front of other members.
Any thread(s) that contain open bickering, name calling, subtle derogatory messages, "digs," personal attacks, or anything negative in nature will be closed/edited or deleted, and any participating members who post in violation of this rule, will jeopardize their posting privileges.
