Can I install shocks after the a-arms and springs are in place or do I need to install it all at once? I've got everything else ready to go back together and I need to get the car back on wheels which can in theory be done this week and long as I can put the shocks in later. For the life of me I just can't remember but I think I should be able to drop them in from the top of the tower. I need to save a few pennies before purchasing shocks otherwise I'd just get them now.
