Just to give everyone an update, today I received my parts from O'Reilly Auto Parts that were ordered as replacements for the subject of this thread. All the brake parts (rear wheel cylinders and rear hose) were manufactured by Wagner and came in boxes marked made in the USA. The interesting thing is that the prices were actually cheaper. The hose was $11.35 from O'Reilly/Wagner vs $17.50 from Carter. The wheel cylinders were $22.83 each from Wagner/O'Reilly and $34.50 from Carter.

The spring bolts manufactured by Rare Parts was also USA made according to the package label and was $29.95 which was the same identical price as the ones that failed at 80 foot-pounds of torque from Classic. One look at the bolts from Rare Parts and you could tell that they were a superior product. They are now installed and torqued without any problem.

I have to say that both companies were prompt with their credits with Classic actually sending a pre-paid UPS mailing label. The point is though that they should not be selling this junk to begin with and even charging the same as what appears to be superior quality, made in the USA parts.
