I am in the middle of a t-5 conversion and am in the process of attaching the clutch assembly to the Fly wheel on my 289 (28 oz). I am using a stock 5.0 clutch 10.5 inch assembly. Only three of the bolt holes on the pressure plate line up to the flywheel. Is this correct?
You need a late model flywheel with a 28 oz imbalance. A modern 10 1/2 diapraghm clutch will not line up with the holes on your old flywheel.
Here is an example: http://cgi.ebay.com/ebaymotors/FORD...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
It will also need 10 mm bolts to mount the clutch to the late model flywheel.
Make sure it is 28 oz and not 50 oz flywheel or your engine will vibrate itself to death
It is different bolt patterns on the 3 finger 10 inch and the 10 1/2 diaphragm.
If you look at the 10 1/2 inch bolted up to the original 289 flywheel with only 3 bolts you will see it is not centered with the pilot shaft bearing.
Good Luck and Be Safe

if you want to keep your current flywheel, contact centerforce as they have a diaphram pressure plate that directly replaces the long style pressure plate used on the early cars.
You will need to either buy a new flywheel or buy the 10 inch Centerforce diapraghm clutch.
IIRC the Centerforce was around $300 when I was deciding which way to go.
I went with the new flywheel and a 10.5 inch King Cobra clutch kit.
