Half Shaft Mystery

[FNG90-195]

I finally got the car home the other day, and have been busy cleaning it up. It's not licensed yet, but it should be in the next couple of weeks. The car is a 1990, #195. It is a Canadian car, 78,000km (about 46,000 miles), and appears to be all original with the exception of JWL A-Molds from 1994/95. Based on what I've read on the forum, 2 indicators of an early car were the glass headlights, and steel half shafts. I have glass headlights, but the half shaft are definately aluminum (checked them with a magnet to make sure).

I have no idea of the history of the car. It has been through half a dozen owners over the years, and I bought it through a shop that had it in for repairs. The shop owner dealt with the previous owner, and he was not too happy about the price he let it go for, so I have been hesitant to contact him.

So, after this rambling intro, my question is : is there a chance these alum. half shafts were intalled at the factory on such an early car, or have they been replaced? It seems very strange that they would be replaced with such low mileage. I found the following part numbers on stickers on the shafts: right side 14041925 - AR8??3, left side 14041925 - AR5033.

Any theories or comments from the all knowing would be greatly appreciated.

Thanks

Mark
