I decided to change the struts & springs in my '73. I took the front end apart and started with the right side. All went well till I tried to remove old strut from tube! After an hour or so of hammering (strut in vise, hammering on forging at base of tube) and a can of WD-40, it came out. put new one in, all's OK. I then went to the left side...much worse. I let it sit overnite bathed in WD-40. After over an hour of pounding, it didn't move an inch! I took it to a local shop and they used slide hammer etc, no luck. Tomorrow I'm going to try to get an assembly at a junkyard. I can't wait to get to the rears! Does anyone have a miracle answer to removing strut cartridges that have bonded in their tubes over the years? I'm all ears! thanks.
