To Compress or not To Compress

[<rtriplett@bjservices.com> (Richard Triplett)]

I would like to replace the rubber bushes on the upper a-arm of my TR-3, 
and was wondering if it is possible to do this by just letting the weight 
of the car rest on a stand, or does the spring need to be compressed...I've 
got the info on making a spring compressor, but looks to me like just the 
weight of the car should be enough to remove the ball and arm and pop on 
new bushings.
