What car accessories? Are they from a Corvette, or F-Body? If I understand correctly there is a newer style pump that should work with both, but I think it needs the newer style thermostat.
PS
If someone has measurements for the Camaro accessories that show where the belt sits on the water pump pulley in relation to the block I will be glad to measure the water pump I have.

Just get the GTO LS2 pump & thermostat. If you at anytime wish to upgrade to a Fast 102 intake/102tb you will have no fitment issues, plus have a separate thermostat housing unlike the LS1

Verdad Gallardo He's running an f body accessory drive.
As far as I know, the later LS2 pumps only had the narrow pulley.

The Corvette, Camaro, Firebird and GTO all share the same water pump, even though they use different depth balancers. The reason the water pumps are interchangeable is that the water pump drive pulley is twice as wide as the other platforms, allowing the belt to ride in 2 different locations. Therefore, you can use either water pump with either platform, although you should check your clearance between your fans and/or radiator.
Not to nitpick, but you omitted the last line:
"04 and later model Corvette platforms use a water pump that has the pulley only as wide as the belt."
An LS2 will be 04 and later, so the vette LS2 pump wont work. But I think the OP can tell by the pics which his is.
And of course we could both be wrong of it's off a Trailblazer or SSR.

lol, here we go again...
There are 3 offsets for belt routing:
Corvette, CTS-V (closest)
98-02 F body, GTO (3/4" out)
L99 10+ f body, Truck (1 1/2" out)
I'm probably forgetting some.
But as far as I know, all LS2 vettes had a pulley that would only engage the vette configuration.
As was pointed out, earlier LS1 pumps on vettes and aftermarket had a wide pulley that fit GTO/F body/vette/CTS-V.
The LS2 pulleys on a trailblazer SS and SSR had the truck offset and would not work with the vette/CTS-V or f body/GTO offset. Double check me on this, pics on Rockauto website.
Now all will bolt up to any block, but you need to take in account the tensioner offset and tensioner used.....
Wanna get more complicated, try adding spacers and figuring tensioner offset. Weirder yet, try swapping pulleys (pic below of truck pulley on f body LS1 pump.
BTW, I see our friend is from down under. I wont even speculate on the Holdens or Utes....

Not trying steal this thread but , but have a question . I have a 08 4.8 LY2 and I want to keep the truck accessories but I need more clearance between the water pump and radiator. The pulley is the big bell style with the long threaded snout for mechanical fan to screw on. Is there a truck style water pump that has the a flatter thin bell without the snout. Something like the bell on the Corvette 04 and later water pump .

O4 Vette & later model Vettes is what the article is referring too.God damn! The 04/06 GTO LS2 pump god damn fits OK!
OP is using F Body LS1 accessories

lol, I honestly have no idea what you're talking about any more/
The OP has f body accessories.
He also has an LS2 pump;
It the pump came off a GTO, it will work.
If the pump came off a vette/CTS-V/truck it wont.
I hope that translates well

I've had several truck pumps, they're all pretty much the same with the threaded snout.
The 2010+ camaro L99 pump is spaced farther out to clear the VVT timing cover and should line up with the truck accessories. Although I think they simply use the same accessories on the Camaro LS3 and L99. The pulley doesn't have the fan threads, so might be slightly shorter. A trip to Autozone to compare the two should tell you pretty quick.
It does have the front facing water inlet, but that can be cut shorter.
