Stovebolters, Thanks for all the help thus far. Thanks to al that I took my old 50 chevy 3600 for its first drive in almost 20 years.
Problem is that when I top 30 mph the whole truck starts shaking. Now it has a 12 bolt rear end that the previous owner put in it and my guess would be improper pinion alignment but I want to know what else to check.
Of course I will also make sure the wheels/tires are balanced but any other thoughts and any ideas how i can narrow this down. Thank you Rob
