What is your location? There could well be someone nearby to guide you through any queries you may have.
Have a look at the A7CA (Austin 7 clubs association) ARCHIVES. You will find copies of the Austin company spares booklets you can print out. Also there are original record cards stating which bits of A7 changed and when the change occurred. You will have found the date and ratio of your axle stamped on the outside of the D casing.
Whilst lots of parts are interchangeable be careful of pitfalls with wrong parts seemingly fitting ok.
Do ask before fitting/removing/ordering.......its all been done before. Some of the many A7 clubs have good websites with technical info.....but be aware of possible slightly bodge remedies......cross check with other solutions people give.
Not all threads are standard......e.g. half shaft and the swivel axles. There is a list of threads in use somewhere that someone did based on a 1932 LWB box saloon.
Cornwall club is another site with good info. One of the members also has one of the original Austin jigs for setting the mesh of the crown and pinion.
The Ruby had more than one type of "D" type rear axles......in all subjects it always helps to say the month/year and chassis number of your car and the part number cast onto most parts.
The very last of the "D" axles (colloquially "the heavy") had some metric size bearings instead of imperial.
The castellated adjuster rings on that axle has a 16 TPI thread and 14 castellations which gives you a 4 to 5 thou adjustment per castle.
You will read in the various books the meaning of the numbers stamped on the end of the pinion and on the crown wheel (for setting mesh).
MY...., no, the wife's Ruby used to do every other weekend runs from Chelmsford to N Devon and back for a weekend home, while I was on a course up there for a few months. Good reliable little cars.
Welcome to the 7 world.
