I think Jegs sells those. Expect to spend atleast 60 bucks on one from them. You could hit the junkyard to find a used one and then take it to the machine shop to get it balanced at the weight you need and turned.

Thanks for the reply. I checked JEG's and I WISH they were only $60. More like $260!! Damn.
Thanks, TJM.......now all I have to do is figure out how many teeth! 164 or 157. Anyone know how to tell other than counting? I have it in the donor car still, but I won't be able to pull the tranny this week and wanted to order the FW to have here by the weekend. Does it matter or should I pick one and buy the right starter for it? Is it most likely a 164?
I love this hobby.....the more answers I find, the more questions that pop up!!!

I have a flywheel off a 302 GT40 Long Block I bought from Ford Motorsport that's never been used. I pulled it off the motor and went with a billet flywheel instead. Let me know if you're still interested and I'll send pics and a price.

If you're using a T-5 bellhousing, then you need a 157 tooth flywheel. The flywheel coice really depends on what clutch and pressure plate you're going to use. The pressure plate bolt pattern in the flywheel needs to match the pressure plate's pattern. The application you're looking for to fit both the 28 oz/in balance and a diaphram pressure plate on a 157 tooth F/Wheel is for a 79-81 Mustang. If you're going to use a Long -style or Borg & Beck pressure plate, then order one for a 65-70 Stang W/ 289 or 302. Or there's a third choice, order the Ford Racing part # M-6375-B302 50 oz/in wheel ( for diaphram PP) and have it rebalanced for 28oz/in. This is what I did for the flywheel I'm using on the 331 stroker in my Ranger.
While it may be a little pricey ($259 in their 2001 catalog), Ford Motor Sports offered two 157 tooth SBF billet flywheels...M-6375-A302 and M-6375-C302. The FMS catalog claims that the difference between the two is either a 4" (28 oz) or 7.2" (50 oz) bolt-on counter weight. The flywheels meet SFI 1.1, and are drilled for the later style 10 1/2" diaphram clutches that use metric bolts and dowel pins. Similar to a previous poster, I had a late-style 50 oz Centerforce billet flywheel re-balanced to 28 oz for the 342" stroker in the 66 Fastback. I wanted the confidence of a billet flywheel and the advantages of the diaphram clutch. The somewhat less expensive option ($107) is the previously mentioned FMS M-6375-B302 cast iron, 50 oz flywheel and have it re-balanced to 28 oz.
OK, I'm a complete novice, totally learning as I go so forgive the ignorance. D Hearne, I will be using a T5 from a 93. I found a 157 tooth flywheel that I can use that is rebalanced 28 oz. I bought a new stock clutch kit to replace the old one. Will this work? I know I should've considered a higher performance clutch kit, but I baby all my vehicles and this one won't be any different. Do you see any problems with this? My setup (see sig) is relatively new and I don't know what HP I'll be pushing, but "guesstimates" are close to 400.
As long as the pressure plate bolts up to the flywheel, you should have no problems. And as you plan on "babying" it, the stock clutch and pressure plate should be fine. I've been running a stock clutch and PP for a 94 Stang behind the 5.0 in my Ranger for almost two years now, and it's done fine, first behind a 325 horse 5.0, then a 400 horse 5.0, and now a 280 horse "high torque" cammed 5.0. This is with a Toploader 4 speed, and a 3.73 geared 8.8 with traction loc and 275/60/15 tires. It's been driven hard every time it's taken out to play, which is just about daily.
2bav8 has the right idea. In my 2004 McLeod catalog it lists the following:
64 - 69 260-289 28oz, small fly, 22-27lbs, 157 tooth, ring gear OD 13.294 Drilled for clutch patterns a.) 10,10.5, 10.95" B&B-Diaphram b.) 10, 10.5" Long & 10" Diaphram c.) 10.5" Mustang Diaphram 1986 - 2000 w dowel pin holes Part# 463100-28
Summit lists it as $256
You can use your 65 starter

What I did..
When I converted my 302 78 Fairmont from a C4 to a T5, I bought a stock, used 86 & newer 10.5" flywheel (50 oz), from an auto wrecker. I then took the flywheel, along with my original auto trans flexplate (28 oz) to a local engine balancing shop, & they balanced the flywheel to the same imbalance as the earlier flexplate. It`s been in the car for 7 years now, still works fine. Also, the stock type "Dynapack" clutch assembly still works fine, despite hundreds of mid 13 to high 12 second 1/4 mile passes. I also have a 85 Mustang 5.0 T5 with a stock clutch, that runs 12.5 @106 mph (1.7 60 foot ), so I think that the stock clutch is a lot better than most people give it credit for.
