looking for discontinued venturi

[harlang]

After about 4 years of trying on and off to get my 7.5hp mercury running right I finally found the problem. One of the little wings on the venturi in the carb is broke off. Now the problem is that this part is discontinued and I haven't had any luck finding one. The mercury part # is 64247. If anyone has this part sell or know where I might be able to find one it would be greatly appreciated.

I think I found one at dollar offshore online, hopefully it is the right part and they dont screw me over
