Robin,

Here are some photos of the cross members and how I took the dimensions:
JPG 1 Shows the plate and cross member, once fitted, you tack weld the plate to the cross sill.
JPG 2 shows the plate on the chassis.
JPG 3 shows the plate and cross sill.
JPG 4 shows all the cross sills in position.
JPG 5 shows how I measured to the holes from the back edge of the frame.

Hope this helps!

Did you ever get your frame straightened?

Andy
