New 914 owner =], First 914 & First Car Options

[OmegaM1A1]

Hey all. My name's Mike, I'm 16, and I was just given my very own (albeit not completely working) 914. It's my dad's and my project car, and I need to know where I might be able to get some parts and what kind of parts I might need. The car will run after we get a new part (I think it's a CV joint or coupling piece or something like that, on the transaxle), and then we need new tail light assemblies to register it and make it streetable.

The part we need, as I said, is a CV joint, coupling, or something like that. Basically, the problem was that a pin somewhere between the transmission and the drive wheels broke, so we took it to the local Völkswagen/Porsche shop and they replaced the pin. Needless to say, the pin broke again because it got sheared by the joint, just like last time. So rather than replacing just the pin, we need to also replace whatever is cutting it. Any ideas/suggestions? I don't have easy access to the car (or pictures, sorry), so I can't get you pictures of a specific area in any timely fashion (The car is 10mi north of my house, I have a pretty busy schedule, and no working car (as the 914 IS my car.))

Thanks.

Oh, I forgot to mention that it's a '74 914 2.0L, 4cyl.
