These straps and brackets should collector items......I believe they were part of GM's first recall.
On December 4, 1971, General Motor (GM) announced it would recall over 6.68 million 1965-70 Chevrolets with defective engine mounts.
The recall covered 1965-69 full-size Chevrolets, 1965-69 Chevy IIs and Novas, 1967-69 Camaros, and 1965-70 Chevrolet/GMC light trucks, all with V8 engines.
On October 15, 1971, NHTSA issued a consumer protection bulletin advising motorists of the potential risks of broken GM engine mounts.
Around this same time, GM President Edward Cole declared that a broken mount was the equivalent of a flat tire or blowout,
and that anyone who could not control a car with a failed mount at 25 mph shouldnt be driving.
A few weeks later, NHTSA sent two staff members to GMs engineering facilities in Warren, Michigan to witness more tests of failed motor mounts;
their findings corroborated the results of the earlier tests.
Around this same time, NHTSA Administrator Doug Toms visited GM headquarters and test drove Chevrolets with severed mounts with GM President EJ Cole in the test vehicles,
but NHTSA did not place a record of Toms visit in the public files.
NHTSA sent a letter to GM on December 1, stating that it was close to determining that a motor vehicle safety defect did exist.
Three days later, GM announced its recall, but the company refused to admit that the vehicles contained a safety defect.
One irony of the recall is that on over 95% of the vehicles recalled, GM did not replace the defective mounts themselves, but rather installed a bracket and cable to restrict engine movement
if a mount broke. By avoiding replacement of engine mounts on all 6.68 million cars, GM managed to cut its recall costs considerably;
the cable and bracket assembly cost about $1 per car, far less than the $50 cost of new motor mounts.
