Hi,

I'm looking for a source for the bolts that hold the engine mount to the firewall. In the parts book they are listed as:

NAS145-15 internal wrenching

I can only seem to find them on Univar for $43 each.

Just Google NAS145-15 and you’ll come up with several sources. Airpower Inc lists them at $30 each.

The NAS part number is superseded. Try MS20005-6, maybe you'll get better results.

Here's a place that has them for $5.86

Awesome! That seems more reasonable. I figured there would be a part number change as the NAS search didn't find many results.
