Give the measurements. Do you have 3/4" clearence with the car down on the ground? I would like to know this info. BTW they are full of it, I am positive you can weld it multiple times.

I have also changed engine combinations and the new engine will put out 100+ more hp and the shaft is only a 3 1/4" dia shaft. Nobody I have talked to recommends it for my application that I have now. This is the reason behind my switch from wanting to shorten it to just replacement. If the car was lighter I could get away with it. Everyones comments tell me that they were simply full of it though.

I must have misunderstood the question.What is the issue of application?I see many big tire,hi hp cars running a similar 3-1/2 aluminum shaft even a few at #3400?We also have many heavy duty,hi torque trucks in our construction fleet with aluminum and aluminum/composite shafts.

I hadn't even mentioned that the shaft was 3 1/4" dia. before he told me that they can't shorten it. Nobody that I called recommended a driveshaft smaller than 3 1/2" and about half of them suggested 4". I want as small as possible though since I have little space in the tunnel with my tubular driveshaft loop.

If this is not done you could, and proably will see a rreduction in service life due to cracking. If the original builder had the driveshaft heat treated and then sold them to the vendor the vendor would have to arrange for welding and heat treating and on a single piece this might cost more than you want to spend. just an idea
