Firewall Insulation

[Beej '86 325es]

Am I looking at the right part here? I want to replace the giant insulation piece that covers the firewall and goes down into the transmission tunnel. But this page looks like it's showing a left and right side, but on my car it's one piece. Is this the right part?

Just buy some Dynamat and cut to fit.

correct, it's multiple pieces, possibly even three if I remember correctly.
