belts
Actually, you might find the belts for less than 15$ for both at the local parts store. Shipping can often exceed the cost of both belts.
Of course, we may have overlooked the possibility that there might be something wrapped around one of the belts/pulleys under the machine...happens.
Do let us know if you have any questions. The first A408 I every did was with two very skeptical ladies watching, several cats and a four year old whom they would not discipline wandering in and out of the area I was working in...and the whole thing (belts, clear sacrifice of one (1) sock to the goddess of laundry, out of the pump, motor-sled wheels and springs) took less than an hour. And I had never done it before in my life.
Have the machine solidly supported when you tilt it back, be sure no idiot can plug it back in (the four year old tried that one, but paranoid as I am, I had already pulled the breaker at the box. Good thing, too - I didn't see it until after I was done. Check that the hose connections in and out of the machine are still tight.)
You will find it was worth it!
Oh, if you get another "ain't no such thing" Or,"we only have parts for the last eight years" in-duh-vi-dual, just keep going through the numbers. A108, A107, A106...A808,A21X, A40X etc. Eventually they will have to admit that there might have been such a beast once upon a time. Or so...
When I can't buy locally (always try to support small business people) I get my parts in the US through
www.applianceparts.com.
They aren't the cheapest, but they have a 24 hour turn around which actually works. And they have always been friendly and helpful when I asked my stupidest questions.
Keep us up to speed on your efforts - bet you will discover you aren't nearly as "un-mechanical" as you thought.
