Are you replacing the entire housing or just the pump?
The housing is casting is durable, but fragile. Be sure bolts go in smoothly and only torque to the right specs otherwise you may crack them.
Use some **** or assembly grease to keep the O-rings on while assembing.
You are going to use an 11mm or 10mm for all the bolts, but you may want to remove the battery box and air box and intake tube to get room to work.
Your hoses are all going to stick good to the aluminum housing so getting those off will require skill and patience. Use a hose tool (or long needle nose pliers) and twist at them to get them loose.
If hoses are original, do yourself a favor and replace as many as you can. They may fail soon after the fix.

I don't know where you ordered from.
I looked up the pump on Rockauto.com. Your AC Delco number matches one of the pump options they offer.
In the info for the pump, they offer an alternate/OEM number of 12494291.
A Google search of that pump number comes up with pictures of the impeller and pulley assembly only, compared to the entire pump assembly as pictured on the Rockauto website.
Clear as mud?

Understood. Just letting you be aware that there is some confusion out there on these critters.
I went straight to AC Delco with your part number and THEY display a picture of the full pump assembly.

DNJ has a lot of parts for our SHO's, but they only seem to have seasonal runs. As is the case for most manufacturers. Get'em while you can is the motto...
Water Pump DNJ WP-4199

If you can find it in stock:
AISIN WP-8950 is the housing and pump. I purchased one in 2017 for $30 off eBay.
