Measured and bolted down at rear wheel wells as per manual. The door sills do not set down on the frame in that door area. Even when pushed down the fiberglass is not down flush against the frame. Am I doing something wrong.[/QUOTE]

It will never be right down onto the frame as one of the vertical variables is how you install the firewall relative to the frame. Regardless, what I had done with mine based on conversations with Tony Zullo and others is #1- line up and clamp the firewall on first, to get that aligned, then #2 - go ahead and add clamps to the top of the door sill area to pull it down and #2 - an additional set to pull the door sill area in to the frame (you may not use the original holes and that's OK and may even be better/easier). Once that is done the last thing to do is play with the rear end, up and down, to get the 45.5" measurement that is shown in the manual. I had done what you did originally and through various emails, conversations and this blog found the way I described above worked very well. You really need to do it in the order I have written it to get the best results for the fit but also to make it easier to fit the door panels once you get to that point. Another point is that the bottom of the body should be flush or just slightly below the frame, this is another validation that its close to be where it needs to be. Another tip would be to make sure the floor pans are not in during the initial fit up so you can use the frame for that vertical clamp (based on my experience ;))

The good thing is that the body is fiberglass and can be repaired very easily unlike steel! Hope this helps.[/QUOTE]
