Ok, after a very quick inspection and measurement of my BDS lifted ecodiesel limited front driveshaft vs a stock height hemi Limited , there IS a difference in length. The Hemi shaft is 4.5" longer. However, with the front drive shaft spacer BDS supplied installed, along with the diff drop they supplied, the installed EcoDeisel front shaft looks identical to the Hemi in every way. In normal mode on my truck compared to normal mode on the hemi, the gaps/spaces are identical between the shaft and the transfer case of both trucks. I suspect the reason for the difference in length may be due to the bigger transfer case the Ecodiesel has over the hemi. I am going to check the shaft angle at the transfer case, as well as look at the gaps between the couple and case in all height modes when I have some more time. I am still slightly concerned, but I believe the kit will be fine. As I said before, my opinion is that the shaft is a different length due to the different transfer cases.....
