I have the BJ tool and a press at homke now, but years ago we used to use knock out the lower's with a big hammer, then use the weight of the car to press in the new lower BJ using a floor jack and a block of wood. Basically just lack it up and the weight of the car will do the "pressing". Now I use the proper tool, but it always worked great.

If your just changing spindles, the upper BJ is all that should need to be changed assuming your lowers are still in good shape. As said before, on the uippers you grind out the old rivets and bolt a new BJ back in. I put dropped spindles on my 71 and the instruactions said I would have to use a 73-87 upper BJ and outer TRE's. My upper BJ actual fit perfectly and I didn't have to shange it, but the TRE did have to change.
