Default LS3 / L92 inspection cover part #?

I have more or less converted my L92 to an LS3 and have a CTS-V T-56 behind it. Since I have assembled this combo, I do not have some small stock parts.

You can see the flywheel between the oil pan and edge of the bell housing on both sides.

I realize the starter will go in the gap on the passenger side, but from another thread on here, I see there will still be some space.

I want to plug the driver side for sure. It is going on an open wheel street/track car, and I think the likely-hood of debris getting in there is worth considering.

Is there a part number for a factory piece?

Is there a better/cheaper aftermarket option?

I was surprised at the lack of info a search provides on this. Maybe I just need a different name for the part than inspection cover.

If you go to this web site you can search for your part number. http://parts.nalleygmc.com/

I would use a vehicle such as a 2008 Corvette with the manual transmission or maybe a LS3 2010+ Camaro.

The LS1 are PN 12558718 and 12561536. They're cheap from the dealer.

Good site! I bookmarked it. It breaks down and has more diagrams than the ones I tried.

Thanks.

In both cases the cover is a $4-5 part. With $10 shipping... The only downside to internet parts buying. I guess I will just need to find more parts to buy to make it worthwhile.
