I'm not sure how to get the pinion angle... but the housing looks straight and its flat on the bottom... if I had to guess id say the driveshaft comes out at about a 6 degree angle...I have it all back together now.. I have a 6 degree wedge and with it all bolted tight the snubber is 3/8 away from the spring... it looks good.. something I noticed that seems odd.. the tire is about an 1 1/2 away from the wheel well in the front of the tire and about 4 inches behind... seems like it should be centered.. ive been having issues since I changed those springs..im wondering if they are just not correct and issues have been adding up since..
