Any reputable spots in T.O carrying Redline products?

I believe I saw Redline products at Performance Improvements many moons ago. No mention of the brand on their website though.

Performance Improvements is still around??

Yeah, performance improvements carry redline products, but you usually pay a few dollars more there. Any reputable speed shop will have it.
Carquest/Karbelt/Partsource to name a few places.

Performance improvements doesn't sell redline any more
They sell the purple stuff. Same difference.
JRP has redline.
Good for transmission, although GM syncromesh is good as well.
