I've only seen one 72 sidemount and it was different to my 75. The 72 appeared to mount on top of the chassis, whereas the 75 mounts thru a boss in the chassis.

600w oil and ep140 are not even close to being the same thing. 600w oil has the consistency very similar to honey. It's thickness allows it to adhere to surfaces. ep140 is only slightly thicker than engine oil. In Australia, 600w oil is very hard to purchase and ep140 works perfectly in my 75.

I'm a believer in taking advantage of modern technology where possible. Spark plug adapters are available to reduce the size of the thread down to 14mm. Then you have a huge range of available heat ranges and technologies to choose from.

I run 140 in my 75 as well.

Yes the 72 should have an SW tank, unless it is a late build 1928. The 75 should have the Kingston tank.

1928 saw the introduction of the Kingston Vacuum Tanks to the Chrysler line up. I think Dodge retained the Stewart Warner whilst Chrysler, Desoto and Plymouth used the Kingston.

I didn't think the 72 had sheet metal on top. Isn't it vinyl over wood?

NPN and PNP transistors both use negative ground. (or they can both use positive ground) Either ground will work for solid state systems. But once the standard was introduced and accepted by all manufacturers the positive ground circuits were phased out. Some early cars did use negative ground, nobody disputes that, but there are no later vehicles using positive ground. The main reason the automotive industry moved to negative ground was to comply with the standard.

Yes there is a logical reason why cars switched to negative ground. And it's all to do with setting a standard by which all manufacturers could follow. It was driven by the Japanese starting in the late 1940s to early 1950s and the development of the huge electronics industry in Japan. And in turn the development of semiconductors. A standard was introduced where all electronic devices would use a negative ground. TV and radio manufacturers accepted the standard early. By the mid 1950s the automotive industry was dragged into using the standard which would allow more electronic creature comforts (like hifi radio) to be fitted to cars. It really doesn't have anything to do with current flow or sacrificial anodes. As a side note: electrons flow from negative to positive, but conventional current flows from positive to negative.

I've never seen production figures for South Africa. The C7 was indeed also manufactured in South Africa, but I was under the impression only sedans were built. Many cars found there way overseas in the late 1980s. Your roadster sure looks nice!

The switch is 19mm in diameter. The hex nut screws off, leaving about 30mm of shaft to go thru the bracket.

I'd have to disagree with the original comment. Clyde Barrow preferred any car that he could steal easily, and I think most gangsters of the day did the same. Yes he died in a 34 Ford and had previously almost been apprehended whilst driving a 32 Ford. But his career started many years before that and Model Ts and Model As weren't known for their speed. Like many gangsters of the era their list of cars isn't known. Al Capone is only known to have bought one Cadillac which occurred in 1928 and it was then armoured. I don't know of any list of his previous vehicles. During Dillinger's best known interactions with police he was driving a 33 Ford and then later a 34 Essex, so I doubt he really had a preference for a particular make.

If you search thru eBay for "2 position keyed switch" you should be able to find something to use. I used this one on my 29 Chrysler: https://www.ebay.com.au/itm/290765574467?hash=item43b2fa9143:g:fBAAAOSwqbxaNY8V&amdata=enc%3AAQAHAAAA8FFvvsoCIKRNS6Vn3yPhz3jVJgHQV5oeFP27%2BSp%2Fchd2nF%2FN8BubxndKWJGYo7CjNcnns%2FjJvARwp3rTfuu%2BrIkITTCMdgtU5S64CDx7L%2BVG6hVpBcaCKB0rtqt3Zjt3lOavdhlAGEylwfPTTHdARpcyBQ1i2rNKsIwLg3U32PxgoMJHOStVeOEsPu43Y9GeVS9Iy5vckaVTfWSjkrJd1cfS4cVCzW8lVyPNxWCeGxbw7ZT%2FCgTRoALjgSNr9ybWdTEBGsQ3Naq7%2FlDzc5GG2JrBkh5iy6HvCdZ1B814bFDSfeBaN%2FGEbnkEH1KLloRONQ%3D%3D|tkp%3ABk9SR4zB3Nn_YA

I've only seen them written in English.

The C5's will be ok. They won't cause any damage. They just may not get the best out of your engine.

The parts books that I have only list the Chrysler part number. 78885 for Red Head 78886 for Silver Dome

I'm not too up to speed on temperature ranges on spark plugs. I think the Champion 20 is also known as a W20 with the 20 being the required temperature. A W16Y may be too hot for the Chrysler engine. (Or is 16 a colder temperature?) Just because it will physically fit doesn't mean that it's the right one.

Vacuum wipers were standard equipment on all Chryslers in 1928 and 1929. It wasn't until 1932 that Chrysler installed a second wiper for the passenger although some export models were equipped with dual wipers prior to then. The first electric wipers weren't installed until after WW2. The model 72 and 75 closed vehicles had the wiper motor sitting outside the car at the top of the windshield, protected by the visor. The roadsters and tourers had the wiper motor inside the car. The vacuum wiper is a very poor system and was typically replaced by an electric motor aftermarket. The original wiper motor was made by Trico and the same motor is used on Chrysler vehicles from 1928 to 1931. The vacuum is supplied direct from the manifold and is not part of the vacuum tank used for fuel delivery. The bracket for the motor is a simple boomerang shape and can be seen in Ben's photos above.

They exist. But are very hard to find.

I'm not sure of the origin of the fold down seat. Alan Waters in Taree also has a fold down seat in his 75, but mine is fixed.

The white faced gauges show your 75 to be a late production car. The 75 typically has gold on black faced gauges.

Nice project. It's my understanding that all export 75 sedans were built in house in Detroit. Holden and Richards only built bodies on the lower priced cars. The 75 and Imperial 80 were all imports.
