Hi Colin,
Great to see another Optima fan out there
From looking at the pictures, here are some things you will need;
Belt drive lexan cover(expensive for such a part)

Stabilizer bar link(complete, not partial, you only need the link)

Gold shock collars

Or you can clean them really good and dye them also
And the correct rear springs.
Maybe you can find most parts here.
Like Keithrc said; "Looks like it'll clean up well Colin, having a straight front brace and lower guard is a bonus too. Looking forward to seeing it all cleaned up and finished."
That's a bonus!!!
