Re: Driveshaft critical speed

Thanks Gents. My truck is a short box with a 1 piece shaft. It also has the 3R type u-joints. Depending on where the engine/trans finally lands, a new shaft will be about 55-56". Going to a stronger joint at the front will not be a problem, as I can just get a slip yoke for the corresponding joint. The rear joint may have to be a hybrid, as the rear axle needs to see a GM 3R joint. Being an Ol'Geezer at 76, my stoplight commando days are behind me. The truck isn't being built for brute power, just good reliability with a little bit of snap. I still like to play, but I also know my limitations. Here's a pic of my truck, so you can see what I'm playing with
