Original Door Seals vs Aftermarket

Author: D. Yates
I, and many others, have had issues with replacement Door Seals.

I bought my ’66 Roadster in ’71 and had not replaced the door seals until recently, so I have assumed the profile of the old seals  (see image attached)  are the “original” profile:- and of relevance to Early Mk I owners.
 

The design of the replacement seals has changed over time.

Comparing their profiles, it does seem to me that closing the door on the “original” profile would produce a downward force to encourage grip and allow the smaller rubber bulb to wrap around the edge of the door cards,  but this would not be the case with the new design- as much of the rubber is squashed up and over the “furflex”/metalwork. 

The quality of the material used in replacement seals varies considerably but the “new” profile show here does seem to be the standard recommended by suppliers. 

The softer rubber used by some suppliers does make it a little easier to close MGB doors, but even these are not, IMHO, as good as the “original” profile .

I’d welcome any views you or others may have on this topic, notably on the actual profile design of the door seals fitted by the factory.

Early Quarterlights ’63 versus ’66

Author: A. Henderson, pic: M. Feig, change over: Clausager, Original MGB,1994
The ’63 pull handle frame is missing the front stub as opposed to the ’66.  Change occured July ’65 Car #65865 per Clausager, “Original MGB”.
 
The vent windows up to 71/72 were chrome over brass and then they went to stainless when they switched to Sicursiv from Triplex glass.  Also there was a change in the vent window handle itself from the early hooked one to the paddle type before they went from chrome to stainless. ’66 on the left and ’63 Vent Windows on the right:

Early MGB “BMC” Grille Rosette

Author: A. Henderson
MGBs for Canadian delivery in 1962/63 at least came with this lovely chrome rosette affixed to the radiator grille just inboard of the left front bumper over rider.  I am unsure as to whether they were present on early Bs for other markets, or whether this was a BMC Canada “extra”.  This rosette did appear on some other BMC products in Canada of early 60s vintage.  Please feel free to comment from other parts of the world.

Early Clutch Master Cylinder

Author: M. Feig
Certainly looking for feedback here on originality.  I am told that the early MCs had mounting brackets holes that were aligned perfectly to the cylinder although this one is not. The Clutch MC from my ’63 has a plastic cap.  Also am unsure what the stamped circles on the body mean.  Comments welcome.

Early MGB D Type Overdrive Under Hood Components and Wiring

Author: A. Henderson
Overdrive became available on the MGB in January, 1963.  The early, early wiring harness contains the necessary connections for the dash switch, and the port for the power feed to the transmission, so overdrive was planned for from the beginning.  (the car photographed has had overdrive added, as it is too early for it to have been factory equipped with overdrive.)
A correct installation includes a relay and a vacuum switch mounted next to the heater box behind the carburetors.  Many early MGBs  with added overdrives do not have these components.  The overdrive will function satisfactorily without the relay and vacuum switch.  Their purpose was to protect the overdrive from harsh disengagement.  The overdrive harness, running from the wiring junctions below the fuse panel to the relay and vacuum switch can be fabricated, and is also available from Moss Motors.
 
Photos show the vacuum line
running from the intake manifold to the vacuum switch, and the correct location
of the switch and relay.  The wires to connect are yellow, and yellow with a red
tracer.

Early MGB Radiator Surround

Author: A. Henderson
One special feature of the earliest of MGB is that early radiator surrounds did not have a large hole on the left side, roughly corresponding to the end of the front air filter for cool air passage to the filters and carburetors.
It is unknown when MGBs switched to the surround with the hole, as again this is a part which is often switched out as a result of repairs to body damage, or when replacing a radiator.  My best guess is somewhere around the car 12000 mark.  Feel free to leave a comment with you VIN # and whether your car has a rad saddle with/without the hole in question.   It is my feeling that cars after approx#12000 to the end of chrome bumper production came with the hole.

MGB Factory Hood (Bonnet) Marking

Author: A. Henderson
Early MGBs to an unknown point had the last digits of the VIN written on the underside of the engine hood in felt pen, or paint pen.  The hoods were removed as the cars proceeded down the assembly, so the hoods were marked to ensure that they were returned to the correct vehicle near the end of the line.
It is quite unusual to see this marking still in place as most early MGBs have been repainted at least once, or have had their engine hood replaced at some point, losing this unique identifier.
Marking pens used seemed to have been blue on lighter coloured cars, and yellow/white on darker colours.  It is unknown how long this practice continued, but certainly to the mid-60s, as the photo which follows is of one of the last of the pull handle cars in iris blue-  #59195

Original MGB Oil Cooler

Author: M. Feig

I believe that this is an original 10 row oil cooler.  Note that the edges were rounded.  A friend just sent me the plate that he believe belongs to the oil cooler.  Ingemar offered up a pic that shows where the plate belongs.

Updated 2/15/12 w/Oil Cooler that has correct Fittings.  2/23/12 w/Pic of plate on Oil Cooler.

Pull Handle MGB Door – Part 2 Interior

Additional Pictures – InteriorFeatures identified include:
Interior Door Locking Handle (This handle has been documented as appearing on the passenger door only, but an informal survey has identified numerous cars with the inner chrome handle appearing on both doors.  No known factory records support this; however the incidence indicates that it occurred regularly.)
