I no matter how hard I look cannot find a technical resource for
Flywheel pressure plate bolt patterns for interchangeability of parts
For engine and transmission swaps.

I would like to know if the 11" clutch I have will bolt up to
A 351W 164 tooth flywheel. And which one will work.
There is no reference that I can find.

The following is the bolt pattern for a 1985 F250 6.9L diesel.
Please post your clutch dimensions here so others can find the info.
Thx.

1985 Ford F250 6.9 Diesel 11" Clutch Pressure Plate specs.

Edit. Note... The pressure plate I have was bolted using these holes.
There are also 6 mores holes on 12 3/8" center evenly spaced. These should mount up to a 351W flywheel.

Thanks for your inquiry. We do not, unfortunately, have a
technical specification drawing of this item. The engine this 14-1/4"
diameter flywheel fits is a Ford 289/302/351W that needs a 28 oz. balance
for the crankshaft. The clutch patterns are: 10-1/2" Long style has three
(3) groups of two (2) bolts that are 3-1/8" center to center on each pair
of bolts, 11" diaphragm style has six (6) evenly spaced bolts that are
12-3/8" center to center across from each other.
