Contact JODY TRANSMISSION to get parallel aligning shims for $79 - he will even refund you if you don't need them. But a must to check and likely needed. And ditch that Browell alignment tool.
I tried getting dowel pins last week from RobbMc but he is out. Jody has them in stock and doesn't charge $20 extra for a set like other shops. And Jody is the most knowledgeable and helpful transmission guy around.
