oil adapter bolts sought

[Steve_K]

if anyone is sitting on gm part 12553513, I need a set of two bolts and seals. I am just a little late to find these on the secondary market.

Working on a Tahoe 5.7 leaking at bolts or the lines, cannot tell which. Ready for the reassembly if i can work this out.

I believe they are 5/16-18 x 4” bolts. Might just try and get some from your local hardware store.

That GM part number is the only way to source the specisl neoprene rubber washer that is the only seal to stop the oil leakage issue. So frustrating for us long haul owners.

I used RTV on the bolts, no leaks
