distance between wing jig posts

I started building my wing jig/posts today. Plans call for "approx. 133 inches," but don't say whether that is between the posts or between the angle iron attach points on the posts. The drawings don't show this distance definitively either. If I go ahead and put the posts at 133 in. will I be OK once I go to put the spar on the angle that will be attached to the inside of the posts?

Thanks,
Steve

Steve,

Check you email, pics sent with measurements

The length of the flanged spar section is 128". Overall spar length is 133". I built my support frame with a distance of 130" between the inside edges of the horizontal angle steel supports. You just need enough space (plus a bit) for the 128" long spar section to "drop" into.
