Any idea what the p/n is for a flywheel for a 1970 250 six cylinder with a 3 speed manual?
It seems they are not reproduced and nearly impossible to find.

I do not know the parts numbers but I have a 69 200 with one on it if it would help.

Looks like 69 up is the same and also Fairlane/Torino. Shouldn't be all that rare. C9DZ-6375-A with a C9DE-A 157 tooth ring gear. According to the 65-72 MPC.

200 and 250 are different animals.
It seems like there should be a lot of cars with a 250 and a manual transmission.
Maybe cash for clunkers got a bunch of them because there doesnt seem to be any around.

Yes, they are. The numbers above are for 250 M/T. Car-Part shows 4, 3 in OK and 1 in NC.

Ive been looking at carpart and it seems they dont know the difference between a flywheel and a flexplate.

Yeah, I just noticed that. Sorry.

Really?
Do you not think that I tried google, partsgeek, carparts, Ford, AZ, Advance, ORiellys, FordSix, Ebay, FB marketplace, CL and a bunch of other websites looking for the p/n and/or a flywheel before I bothered to come on here and ask for help?
I spend whatever time it takes doing research when I need an answer. I only ask for help when I am at a dead end.
The 250 uses a zero balance 157 tooth flywheel. A SBF uses a 28oz or 50oz imbalance flywheel.
If I cant find a 250 flywheel I have four choices.
1. Buy a SBF flywheel and have it machined to zero balance. Not cheap
2. Buy a SBF flywheel that has removable weights. Not cheap
3. Buy a 300 flywheel. The 300 is zero balance and 164 tooth, so different bell and clutch. Not cheap
4. Install a C4. I own everything to convert from manual to auto, so no cost.

Did you ever find a Ford part number?
In years past, there was a "junk yard hot line" where you could ask those on it to see if they had what you needed.

The correct 157 tooth flywheel for a 1969 250 is a pretty rare item to find. P/N C9DZ 6375-A. Usually you have to buy a whole 1969 Falcon to get one.
Corrected P/N on edit.

According to my research the correct part number is C9DZ-6375-A with a stamped or cast number of C9DE-A or C9DE-B 157 tooth ring gear M/T-manual transmission. The C9DZ-A flywheel was used on 250 engines with a manual transmission up until they no longer produced a 250 with a manual transmission (maybe mid 70's?). According to the O.S.I. manual there was no replacement or supersede number for this flywheel.
I have a 1973 Mustang convertible parts car that was born with a 250 engine and a 3 speed manual transmission. I can check tomorrow to see if the flywheel is still with the car if you would like.

Was trying to help.
Your initial post was pretty generic. "Help me, I can't find a replacement".
If you had shared all of this prior knowledge at the beginning, we could have cut to the chase and been looking for a Ford factory original flywheel.

Same here. I looked up the part numbers and did a couple of searches based on them. I found nothing. I can appreciate the frustration involved, but if more information was included at the start of the post it would have made this a lot (yes, it is two words) easier. This is a common factor, the original poster leaves out a lot (see above) of pertinent research they performed. To be truthful - it (censored).
