I am wondering where you are located not that it really matters. I'm guessing Europe?
Anyway...
I already know the propeller shaft part number is 9143292
You are not planning on replacing the entire driveshaft, are you? You only need to replace the worn parts unless there is obvious damage.
One very important thing to know is you must reassemble the shaft in phase. This is easy to do but if not done properly you will be removing the shaft again to correct the situation.
Before you take the shaft down look for the arrows imprinted on the two parts of the shaft. They may be hidden by years of grime. You can see them in the exploded diagram below. On reassembly make sure they are pointing directly at one another or you will experience the same sort of vibration you are already familiar with.
However, I want to visually verify all the part numbers before placing any orders.
You will want to get the correct parts, of course, but I don't think you will find any part numbers on any of the parts in question. There will be two different sizes of u-joints. The forward (unless there is a flex disc instead) and middle u-joint are the same part. The rear u-joint is larger. They should have a grease fitting and you will want to lubricate them from time to time. I have always preferred to remove the zerk replace it with a plug between lubes but that is not a requirement.
