I emailed Dennys Driveshafts and he felt like I would have some issues especially with the shorter than normal shaft.
I am going to raise my transmission to help reduce my angles as much as possible. Here is our conversion:
Denny: With short driveshafts it is very important to have everything inline and no offset at all.
You will need to install a rear end that has the pinion in exactly the right place to allow for a straight line from pinion to trans.
Me: While measuring a little more I realized the over head net difference is more like 1.25" due to my engine and transmission being mounted offset.
I am planning to go ahead and use this rear end. I was thinking about bringing the transmission up to decrease the driveshaft angle.
Any thoughts? Thanks!
Denny: Get your angles as little as possible so the total amount of offset will not cause too bad of a vibration. Technically you should have vibration with that short shaft and compound angle. You might get lucky and the offset may not react so badly.
