Taking my transmission apart, I found the flywheel bolts are not stock, except for one. Looking at it, it's a GR8 but with slots in the head instead of the usual raised marks. Doing some research with the parts manual, I found it is a GM type AA six slotted head GR 8 bolt with 300M steel. Searching in the net it seems AETNA makes these exact bolt. I'm assuming they won't sell me 6 units. Have any of you bought these bolts before or have you used standard Gr 8 bolts UNF?. Appreciate any help.
