I just purchased a Fundo K-5 wheel on Ebay and noticed the wheel does not have a hole between the lug holes as my other ones. The '88 900 has a wheel designation of Fundo K-3. The diameter is the same as is the wheel pattern. I was wondering if I could get it to fit by just drilling a 1/4" hole to fit over the protruding post on the car?
Well, since he already posted to the newsgroup, he can hardly undo it... oh, wait, you meant the post on the car.
Never mind.
or just undo the post?
I had a car that used lug bolts and no post. Putting the first bolt in while holding the tire was challenging. It was best done by sitting down and using the feet to help hold the wheel in position. This works when you are young. The post helps align the wheel. I guess I could just call AAA to change a tire - Not!
A side question - any idea why Saab changed from studs and lug nuts to lug bolts?

Same thing puzzled me momentarily. That post is one of the two bolts holding the rotor on - replace it with the flat-faced type bolt that is for the other bolt, that takes care of _that_ problem. However, What does Fundo mean by the -3 vs. -5? Could it be wheel offset, in which case this would be a bad wheel to put on the car. If the plane of the tire is too far in, _or_ too far out, handling and all sorts of other problems could result.

Back in the Saab 93/95/96/97 days, they used lugbolts as well. Instead of a post, there is a large cast ring into the face of the hub (or drum) that you hang the wheel on, which the ring on the wheel lines up with. Fronts spin fine, because the tranny keeps the axle from turning while you line it up, and the back doesn't move at all because the handbrake is on when you change tires. Actually works better than the post as far as I'm concerned.
As to why not use studs at all, well, I assume it has to do with making a critical part with a more reliable and fixable design. Replacing a broken stud involves special tools _and_ the part, and a stud & nut, compared to a tapped hole, is more failure modes which could cause big problems.
