Thanks for the reply and help. Yes I have measured this correctly. this is a static drop and I am loaded so to speak. I have a cover on the rear so it has lowered it a little more. It is pretty obvious of the upward point of the rear end (pinion) and when the drive shaft is installed you can see the angular difference between the two.
I really don't have much room to move the tranny around and I think the angle it is set at is correct. It is EFI. Also I understand what you are saying but moving the engine tranny combo will somewhat change the drive line angle but it will be minimal and it still wont get the two angles much closer. My best option is to remove the rear and do some cutting and re-welding. I have cut everything else up on the old girl so I might as well do this one too. I dont think any shimming will help to the extent I need to come down.
I did see the Hotchkis kit before and I agree I am not sure why my angles have gotten so extreme. That was in part what my post was also asking but regardless it is off and needs fixed.
I had went from using a drop spring and spacers to get my drop and now that I changed the springs it is worse. It was higher than i wanted before but not as bad.
Again any other thought will be great. I will get out there and remeasure but I know I am not off much if any.
again thanks
Dave
