I have a '35 1200 Max Merrit tells me the water pump gasket varies by vintage, not sure if the engine is original, does the attached picture with numbers on he engine case indicate a manufacture date? Number is 389005 C

I went to the mechanics today to pick up my car, it had the rear end upgraded from a 4.69 to a 4.06 so it can be driven a bit faster without damaging the engine. Thing is it changes the ratio of the gear drive for the speedo. When the speedo says 50 my car is actually going 60. Is there a way to change the speedo drive to fix the indicated speed new gears, recalibrated instrument?

I've purchased a new higher speed rear end from EDL services for the '35 1200, and the shop doing the work is telling me there is some amount of grinding needed to get it to fit the case, so I've told them do that carefully. They are telling me that even after the rear end is installed the original rear end was shimmed up and the concern is the shims needed for the new rear end would be different. Is there likely a source for the shims or would these need to be made?

Thanks Owen, I think what I was saying was based on a misunderstanding on my part the folks I'm speaking to just have the diff and not the axles however I will pass these details along so they have them, Best

Looking for a little help locating bearings for the rear axle of my car. Rear axle is 4.69 rear end. I have the car at a service provider that specializes in rear axle work for trucks. He's attempting to locate the bearings which I understand are dual row ball bearings. Was wondering if anyone here would know a source for these. He Tried Max Merrit and I believe he tried Kanters also, so the obvious choices but apparently no luck so far as they are rather old, anyone aware of a source for these? Thanks!

Appreciate your suggestion Owen, kind of a tight spot I'm hoping you recall did the numbers I'm looking for appear on the backs cover (carrier?) , the axel housing, or the front side where the drive shaft enters the diff. Hard space to fit into a little suggestion would help, many thanks!

I have a '35 1200 sedan would there be a staped or other wise indicate value for the rear end ratio in the car. I've heard about counting revolutions just would be nice if it was indicated on the car somehow?

Just an update I had a fellow with a 56 exec check his flasher it was a tung sol 273 D, I found one on ebay and that functions properly inside and out so thats the missing item to correct the issue I was having...

Getting back to this now, I have some questions and am little lost.

I have the following situation now, both indicator lights are on when the car is started, the indicator opposite the selected side on the dash lights when a turn is seleted. Left blinks when right is selected left stays on and vice versa, however externally the signals work correctly.

To clarify:
" The dotted lines are only meant to differentiate the 49-52 single bulb indicator circuit from the 53-56 dual bulb indicators." so the dotted lines are not wiring in the circuit?

So if I understand correctly If I selected a right turn, the orange wire would be powered, and because the left front signal light is not powered there would be a ground through the left dash panel light and the left dash indicator light?

"Functionally, both indicator lights get voltage from a separate contact in the flasher at the same time the flasher sends voltage to the outside bulbs"

The flasher normally just turns on and off (Blue wire?) the switch has contacts the send current on side or the other. I see the flasher has a separate contact pin 2. Does that pin provide + 12 or ground? Seems it must be +12 to make the 49/52 indicator work?

This starts to make sense in terms of seeing both dash lights on, seems to me a ground connection to the dash indicators (dashed line if a physical wire?) would solve my problem. getting a ground thru othere lamps makes no sense as voltage distributes across all loads. So I still have my previous question what is the path to ground if its through another lamp that's a problem...

Thanks for your response, the diagram confuses me some, there is a dashed line between the panel displays on the side of the blub I would expect to be grounded, what is it that's going on there? it appears that it means its there on later cars so the current path is from the turn signal switch (ie orange wire) thought the blub to flasher to ground? is that correct?
