How many of you are experiencing failure/vibration? Contacted a local reputable driveshaft builder, and he told me the length is too long for one piece. (Even with a 4" tube) said it will be fine as long as rpm doesn't exceed 3000. Lol. No good to me. Worse if I ever go with an overdrive unit. The more I read about it... Seems he's correct. At critical speed the shaft may bow and "whip" around. I did this conversion to a '72 gmc years back. Didn't notice any issues. Link below to a well known manufacturer... With a calculation table. Won't work according to this.
