360 Flywheel question

Alright, I did some checking. My 1976 360 crank is drilled and even has an old bushing in it. So I'm good there. Checked flywheel, no #s to be found on it. But I know it's from a 1968 318. With no add on weight kit available for it, so I'm leaning towards getting a new 360 flywheel. Only ones I've found are over 300 bucks plus shipping. Looks like Brewers has neutral balance with a mod for the cast , looks like they are a little cheaper. Anyone have one they want gone? Lol
