I set mine up at 37 inches but people do differ a little in design

I have a 30 model A with a professionally built TCI frame and a corvette rear end, so this information may not completely apply to your situation, but maybe it will give you a starting point.

The coilovers on my car are Alden brand and measure 12 inches from the top to the bottom mounting point. The coil overs are mounted at an angle. They are exactly 31 1/8 inches apart at the top (off the frame) and 41 1/8 inches at the bottom, connecting to the trailering arm of the suspension.

Hope this information helps.

It depends on the type of four bar you are using. Typically the frame mounts for the four bar will dictate location, if you are not using a "pro street" set-up. Some of the "pro street" set-ups fasten the front mount to a cross member, allowing you to install it wherever you need it.

If you have the traditional Pete and Jakes style fourbars, when your front brackets are in position on the frame then you can tell where the rear mounts will go on your rear end. Before welding your front brackets to the frame however you need to be sure that where your axle goes on the rear bracket , that your axle is going to be centered in the rear wheel well.

I agree with Lakeroadster. I just installed a 4 bar in my 30' coupe, and I found that by first positioning the front mounts to frame the rear mounts were in the correct position on the rearend. My rear is a 9" Ford and I made sure it was centered before tacking everything into place. The spring-over shocks were a different story however. The rear mounts had the shock mounts built in and the angle of the shocks is right at 30 degrees when installed. Any lesser degree interfers with the frame. I'm not real happy about this and may change it later.
