Were 10-24 keps nuts or stamped, machine-thread nuts used to hold the lower dash pad to the dash? The assembly manual specifies this nut as 45245-S36 (5 required) but I'm not able to determine what type of nut that is. AMK supplies this nut as a stamped nut, yet I'm not sure that's correct. I'm 95% certain my original lower dash pad was held using keps nuts and I'd like some feedback as to what others have seen.
