To everyone that replied I should have been more specific.
I test fit one part to another part all the time. What I am referring to is I build cars and I like to customize them. One thing I always change is ride height. Fortunately I have been lucky and I usually get it right with some eyeballing.
I want to be able to put the front and rear suspension together and the wheels and tires on it. That hotrod might not have been the greatest example because that guy scratchbuilds and uses pins to hold everything together. A car kit doesn't stay together like that.
So I am essentially asking if there is a way I can glue a car kit together and still be able to disassemble it.
