Re-use flywheel torque to yield "stretch bolts"

[sorka]

I'm in the middle of a clutch job. Was about to re-install the flywheel when I ran across a post by someone saying that the bolts had to be replaced because they are stretch bolts.

However, TIS says nothing about replacing the bolts anywhere. It just says to torque to 38 ft lbs, wait an hour, and then turn 90 degrees tighter.

I called a local Toyota dealership here in the Bay Area and they had none in stock. They checked the stock of all the other stores in the south bay and none of them have any in stock. They checked the dealerships all along my way home and none of them had any in stock.

Given that I'm inclined to believe dealerships just re-use the bolts. Any thoughts?
