Flywheel Question on casting #s and what they fit

I have a flywheel casting # 2848212 and there is another # on it 85276. Can anyone tell me what this came out of. I checked the index at the main page and they tell you bell housing #s and body specs but no flywheel info.
Thank you in advance.

That casting number is a 143 tooth flywheel used on '67-'69 383 and 440 passenger cars and the same year trucks with the 318 and 383. It is drilled for an 11" pressure plate.
