Water Housing Assembly

[vans]

I need to replace mine, slow drip turned into a chunk of metal broke off threads where blue drain plug goes in.
5.7, 350 mag with Bravo3

Question
I've determined pt. no. 863631T1
OEM prices range from $270.-$310.
but good ole Amazon has what appears to be a direct replacement for $30.-$70. dollars
I hate to be cheap but that's a lot of money, just wondering if anybody else has been through this?

Clarification
Water Distribution Assembly, looks like 4 hoses go to this
