Wayne, we installed the AutoKraft pan on the LSX454 in our 69 Camaro. We did not have the bolt hole issue you recalled in your OP.
The pan also bolted right up as mentioned by others. I don't have a great picture of it installed. Only a few glamour shots from the build thread but none specifically of the oil pan installed. I'll take a look back through old photos and if I find anything I'll post it for you.

What u are asking about is on older ls engines, mostly truck engines the 3rd or 4th bolt from the back on the driver side was never drilled from the factory. It never cause any leak issues on factory pans, but i do not know about after market pans. I will check my blocks i have here and try and find an example of such
It must have been on the older motors because everyone that replied said it was not a problem for them. I have a new crate engine so it wouldn't matter on mine. I was just looking for information before I had an LS to check out for myself.
