dana spicer universal joints connected with regular halfshafts.....

CV joints are better due to the angles involved....you'd also have to have a 2-piece axle with Universal joints or transmission input shafts that "floated"

CV joints are a much better design. U joints wear out rather quickly. They also "normally" live between the trans and the final drive, so they see 1/4 to 1/3 the torque.

You can still get them rebuilt, or upgrade to better CVs. I bet it's cheaper to upgrade CVs than to devise a ujoint setup. (remember, the length of the shafts changes with suspension movement.. Ujoints don't do that)

okay, then you'd have to pick a universal joint that will never go out of production and would be stocked "everywhere" with that logic.......does not matter what kind of car you drive..there will come a time when you have to special order parts....times change and so does the stock room at the auto store....besides, how often do CV's fail?? not very often......with cars this old, it's either have spares or deal with having to have parts delivered.....

Another axle option, not sure you guys may be aware of. Todd Francis at Precision Alloy Ltd. can modify standard stub shafts to make T2 CVs a bolt on deal. Fit a set of 33 spline SAW axles and you're good to go. The SAW axles are supposed to be a bit more "springy" than standard, providing a little more "give" for absorbing torque.
This isn't the lowest dollar solution, but it would get rid of adapters, provide a stronger readily available 100mm CV and a little more give in the axle dept.
Todd did my 914 trans output stubs for about $100 - excellent work and delivered with a nice and new looking black oxide finish. I don't see why he couldn't do the same with the outboard stub axles. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

I'm told to use these properly on a 914, spacers are needed because the 911 axles are a bit shorter than the 914 axles. I've also been told that they'll work just fine as-is (they were running without spacers on the parts car).  Can someone give a definitive answer to this question?

the 911 axle shaft is about 1" shorter. it'll work fine if you intend to run your 914 on the racetrack only.

it's pretty easy to imaging what will happen if you hit a bump on the road with a axle shaft that is 1" too short.
it puts the CVs under "preload" as they're already almost fully extended with the car just sitting there ...

that's why i went with the 944 CVs and the stock axle shaft ...

I thought it was ok to run the shorter axles, is Brad's info only applicable to racing? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Where can you get a hydrolic clutch setup or does it have to be custom?

not good unless your shock travel for the street is about 1" or so and you're never ever going to hit a bump ...

brads quote:
"We have raced the cars for years without the spacers."

on a racecar, you don't see as much shock travel, plus the road surface on a track is usually less bumpy than the average CA highway ...

i wouldn't recommend to run a axle that is 1" too short on the street. for obvious reasons.

but hey, it's your car!

ok, 1st, welcome to the club.

second- lets go through a logical thought process on this.

ill ask you "whats the weakest link in your current method of getting the power to the pavement?"
you say "The CV's and AXLES"

now, what happens when you beef up your weakest link? what is NOW become yuor weakest link????\
YOUR EXPENSIVE TRANSMISSION

i dont know about you, but id rather break CV's than have to rebuild a trans.......

your mileage may vary

Hi, Gary welcome to the club.

And Aaron, I just wanted to say, very Logical statments concerning beefier axels and cv's and tranny's. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)

And, as for universal joints, couldn't keep them in, the mid engined SBC (302) powered corvair, and when a U joint went, that drive shaft would scare the piss out of the dead, and when it stoped flopping around in the car, the car would drop where it stoped and wouldn't roll any more.
