What is the easiest way to replace 68 sub-frame bushings....hopefully without removing the entire front clip.

jblake, You can do it without removing the front clip, although you'll have to do some "fishing" with your fingers and such when doing the middle set. I've done it both ways. With the clip in tact you'll need to lift the car via the subframe. Remove the rear and middle bolts. Then using floor jacks and some thing to displace the wieght, like a large board, across a large section of the rocker panels, lower the subframe down, away from the shell. You now should be able to slip out the old rubbers, washers and spacers. Slip the new parts into place and slowly jack the subframe back up to mesh with the shell. Get your bolts started and secure. Repeat procedure for other side. I'm not sure about the bushing under the core support. I've only replaced these with the clip dissassembled. Buy a complete kit for the job however, you'll most likely find your bolts are rotted thin along with fragged out rubber bushings and washers. Good Luck.

Thats the way I did mine too. Just last Sunday

I did mine a while ago and had to weld in new metal on the subframe. Because of the front mounts I was not able to get enough room by just undoing two mounts. What I had to do was remove the three on one side then jack the car up from that side, install the bushings and then rebolt everything. Then I did the other side. One point, make sure the steering wheel shaft does not bind while jacking the driver side up. I had to unbolt mine to get room for the body to move up.

Definitely order the whole kit (bushings and hardware). I was going to reuse mine but a couple of "cylinderical Washers" spacers came out in chunks of rust as well as some of the big washers. It set me back the mailing time to complete the job. pdq67
