2010 Monsoon350 Thermostat Housing

[jjk94]

I’m looking for the part number of the thermostat housing. Indmar catalog only goes back to 2013

Does it look like this? This one is off an ‘08 340 monsoon. I would expect that they are the same as both are GM 5.7L Indmar engines. 
 

If you think this is it, then I’ll make you a deal that you can’t refuse, as I replaced mine with a different style due to another issue and it just laying around.
 

PM me if interested

Thanks. Didn’t realize the part number was clearly on the part

The link given by uk_exile shows a different THERMOSTAT HOUSING ASSEMBLY than on my US model 2012 Malibu maybe because this is a AU link?

I am thinking of using this gasket https://www.amazon.com/Thermostat-Housing-Gasket-Aluminum-Silicone/dp/B0B6VJ5VWP/ref=cm_cr_arp_d_product_top?ie=UTF8

Does anyone have any knowledge of using a gasket like this - tired of replacing the cardboard-style ones.

I just used red, high temp, gasket maker and made my own when I changed my thermostat. Seems to be working just fine.
