1928 Intake Manifold

As far as I can tell there were five basic versions of the intake manifold in 1928. It's important to note that an important distinction of 1928 intake manifolds is they had 1-1/2" counterbores for gland rings at the ports just like the exhaust manifolds. Using the notations on the pic above I believe the variations are as follows:

1. Intake type #1 with mounting ears style #1 (shown)
2. Intake type #1 with mounting ears style #2
3. Intake type #2 with mounting ears style #1
4. Intake type #2 with mounting ears style #2 (shown)
5. Intake type #1 with mounting ears style #1 with the addition of an embossed vacuum hole similar to later manifolds.


Please note the first four types have no provision for a vacuum line. Intakes 1, 3, and 5 have mounting ears style #1 which WILL make them '28 manifolds with counterbores and can be identified with certainty while on an engine.

Ok, here is the help I'm hoping for. I'm looking for actual examples (pics) of intake manifolds 3 and 5. Additionally if anyone has any of these types AND feels the manifold is original to their engine, please let me know the manifold type (1-5) and the engine number to help determine the time lines.

1928 MULTIPLE DISK CLUTCH

1st Cover - Multi-Plate Clutch
2nd Cover - November 1928 until March 1929
3rd Cover - March 1929 to the End

Question:
I have acquired an early 1928 phaeton which I am currently restoring. Of the little material I have read, I get the feeling I shouldn't persist with the original clutch but should get a later single disc model. For the record I like the purist thinking but it is unlikely I will show the car; I would rather drive it. Your thoughts please???

Answer:
If you plan to drive your Model A I would suggest you put the later single disk clutch in. The disadvantage of the multi disk clutch is that oil from the rear main would get into the clutch assembly and mix with dust from the clutch disks and cause the disks to hang up in the flywheel. The clutch would also chatter because of problems with the disks releasing. That's why Ford changed early (about Nov 1928) to the single disk clutch. It can get rather expensive to rebuild a multi disk clutch. More than just the clutch is involved. It will also take some doing to change it out because of major differences.
To change from a multi disk clutch to a single disk clutch you must replace the flywheel, flywheel housing, pressure plate and clutch disk, and transmission. The early transmission for the multi disk clutch had a different front main driver gear and shaft and no throw out bearing. The early transmission case was not tapped for the bolts that hold the front bearing cover, which is a snout (housing) for the throw out bearing slider (hub) to ride on. If you get a later transmission, make sure it has the front retainer which is the slider snout for the throwout bearing, and the throwout bearing hub.
