as far as 162 tooth The FWD Riviera uses a different starter.
You are using the starter from the Riviera right? It looks different from the RWD ones.
But if you are using the RWD starter you can use the 4.1 RWD flexplate.
If you need more help or are still a bit confused, let me know.

Glad to hear you sorted it out.
Let us know how it works for you.
P.S. I have a 4.1 flexplate in nice shape laying around if you need it.
