need help finding a hks base plate
 

I'm trying to find where I can buy the inlet base plate for this hks 40mm wastgate. I bought this from a member really cheap and he told me that he didn't have the base. But didn't think it would be so hard to find. The only thing that I found is the part # 1499-RA085 but don't know if this is the right one.
