The alternate number WW90183A refers to the same physical part, so if your old parts book or a box of spares shows that number, you're looking at this same block.
Our record on this one is brief — we don't have more detail beyond the basic description, so if you're matching this to a specific carb setup, best to compare the physical part or call the shop and we'll help confirm before you order.
