KILLew,

I have a question for you regarding your info on 75-77 trucks.

You state that all had cats except 76-77 454 V8's. Do you mean 75-77? I've got a 75 silverado C10 with a 454, and I have no indication that it ever had cats. Also, it would seem odd to have 75 454s with cats, and then remove them for 76-77.

Thanks,

Brian
