Hey Steve,

sure thing. Typical headmarkings are J, L and RBW.

Definitely 6-24. Here is the set Rick's sells, but they don't say whether they are technically correct. I removed some from a pace car 25 years ago, and they were allen head, but no way of knowing if they were originals, as the car was already 16 years old.

We ended up using 8-32 screws in an NPD 69 camaro reproduction cowl hood.

Maybe the repro hoods have 8-32 threads but original hoods have 10-24 threads. Glad you got what you needed.

Doh! Must have been late. Of course, I meant definitely 10-24. Man, gotta get some more sleep.

Here are a couple pics of my original cowl screen screws.

Those are Chevelle. The poster needs to see 69 Camaro flapper door screws.
