As I recall the dimension from the center of the turntable to the front wall of the roundhouse is printed in a small drawing on the back of the box the roundhouse came in, do you still have the box? The drawing shows a 90' turntable, but the distance from center point to front wall will be the same regardless of tt size. I used a 105' tt, so my roundhouse is closer to the pit than it would be if I had used a 90'er.
I did as David suggested above, and assembled the bases together. However, I did also build the turntable to the point where I could drop the pit into its hole, and the bridge to the point it could sit in place. Then I was able to glue rails to the bases, I left them a bit long and trimmed after final installation, using the flat side of a Dremel cutoff disc to grind the rail. You can see in the photo I posted that I also soldered leads to the underside of the rails prior to installing the roundhouse, I actually did so prior to glueing the rails to the bases, makes life much easier, IMO.
