New driveshaft

Often times, a customer does not leave a return number on my answering machine. When did you call me? I can check the transcript.

Sounds like Summit didn't tell you Strange driveshafts are delayed at least a couple weeks due to a shortage of cr-mo tubing.

In addition, I'm not sure how buying a driveshaft assy from Summit will save you almost $100 over my prices (see below):
