Simple fix for a severe and self perpetuating catastrophic chain reaction in 67-69 Camaros with V-8 engines

When the driver side mount broke, engine torque made the block lift up, and pull open the accelerator linkage.
This caused an increase in pull on the throttle to the carb, causing increased revs and more torque twist to the engine, and with more upward movement causing more runaway acceleration in a vicious circle.

This runaway sequence would only stop when the engine hit the underside of the hood.

But that wasn't all, the twisting upward engine pulled the power brake booster vacuum hose loose, making it harder to stop the car, and if that wasn't bad enough... the twist also caused a problem with the automatic transmission, which would shift to the right, with a result of the car no longer having a park position and being able to start in reverse.

New motor mounts cost $50 a unit, and so GM fixed the issue with a $1.00 bracket and cable to hold the engine down if/when the motor mount broke.

Consider that the problem caused a 6.68 million car recall, then multiply the number of cars by the cost of the repair part, and you can see why Gm went for the cheap simple fix.

I learned all this from the May 2012 issue of MuscleCar Review, page 24

(1 of 206) 1969 Z28, JL8 optioned, stripe delete... was sold in 1977, and finally bought back in 2010... wow! Home after 33 years, with only 22,133 orig miles

 Original everything, paint, interior, hell... it's probably got 1969 air in the tires!

the second owner put it in the garage in 1982... and left it there... BARNFIND!

this is a X-33 car and was ordered with custom (deluxe) interior, fold down back seat, radio delete, headlight washers (only 116 non-RS cars were ordered with this option), and rear window defroster.

Tom sold this car in 1977, located and purchased it back in Feb. 2010.  Not only is it a 22,133 mile 1969 Z28, but it is a rare JL8 Factory Option  (Four Wheel Power Disc Brake 1 of 206) and a Stripe Delete car.  He still has the Warranty Card & Protect-O-Plate that he kept when he sold the car in 1977, not for any reason except they were not important back then and rarely did anyone ask for it when they were purchasing a car from a private party
