Drive shaft tore off! flex joint disaster.

[chevy43]

My girlfriend was driving her '78 240D and the drive shaft tore off the manual transmission at about 30 mph. It ripped two shift rods off the shift linkage broke the spedo cable and bend the cross member a little. That's all I could see so far until I get it jacked up. The tail shaft and rear housing seemed ok.

There was no noise or anything to warn us something was wrong.

I didn't know that those joints could just fail like that but I do now.

I think I can fix it for her if I can find new shift linkage rods.

Can anyone tell me where I can get a set of shift linkage rods for a resonable price?

Thanks,
T.
