I have solid body mounts, as well as sub frame connectors.

I'm very happy with the set up. Keep in mind that I have a whole lot of aftermarket add on's in combination.

I would watch out for some of the connectors that are bolt on as they sit very low.

I went with weld in and punched up the floor to get them up as my car is very low!!! The bars are visible, boxed and covered by carpet for a clean look.

 

I had to realign my front fenders when I put solid bushings in my '71 T/A. However, the stock rubber ones were so bad, the bolts that run trough the middle of the bushings were necked down to about half the thickness that they used to be. The bushings were absolutly the worst, most dried up, splitting apart, pieces of crap I'd ever changed out. The car was so flimsy I couln't open the doors if I had a floorjack under the front end. However, the gaps and panel alignment didn't look that bad when the car was sitting on it's wheels. Not sure if some time before I got the car the fenders had been adjusted as the car "moved around", I don't think so though. When I got done putting in the solid bushings I did have to take off my hood and realign the front fenders, etc. I think the fenders would have needed realigned even if I had replaced the bushings with stock rubber bushings. If I were you, and my stock rubber body bushings are in good shape, I would not go through the hassle of putting in solid bushings. I had to replace mine, so I figured why not go with the solid bushings. I did it without chipping any paint, but I came close a few times when testing that the doors open OK.
