I was just wondering how this was going for you??
That looks like a Chevy Core, but they might have used them in the later Pontiacs with the 2.0 OHC.
I thought I'd dig up the old thread where I labored to no luck. Might be a bit or 2 of useful stuff for you in there Paul.

GREAT new Sig, by the way!!
.
I am gonna pull mine and start comparing once I have something to look at.
that looks just like the one i pulled out of mine. my replacment was a little diff and i had to trim the cover to make fit
Looks like the core I pulled out of my wagon yesterday, except the one I pulled out had two plastic tanks like my radiator has. I wonder if it was original... It looked brand new, but every time I'd fire up the car after it sat for a couple of hours or more, I'd get a whiff of coolant.
The replacement core was all aluminum this time.
