'32 rear crossmember early vs late

[19fordor32]

I'm sure it's out there but I've searched here and the HAMB and lots of references to late '32 rear crossmember shorter to account for the reinforcement plates and early is wider for lack of braces but can't find measurements or anything to identify one or the other.
A little preface I am putting a stock frame together, I have a cherry K member, rear crossmember and rails but all from different frames. I need to figure out which rear I have as I'm willing to fabricate the braces, unless anyone has some to sell?

The rear crossmember from a reinforced frame is shorter side to side but also top to bottom where it fits into the rails. If your rear crossmember is a snug fit into your frame rails without reinforcements than its a match, if its loose than it's probably a late crossmember from a late reinforced frame.

ionia hot rod shop ionia mich fabricates very presentable 32 ford frame reinforcements.

That Ionia, MI shop also has a sophisticated set of fixtures to measure and straighten as necessary any deviation from original in '32 frames, such as the typical deformation of the frame rails at the top of the kick up caused by bottoming out on the rear axle housings (before the reinforcements were added, first outside, then inside).

I could be wrong, but I think towards the end of 1932 there is a factory service bulletin on replacing the rear crossmember and adding the reinforcement plates. There are definitely two different rear crossmembers. That article might give the measurements of the two different rear crossmembers. I was building a frame years ago and ran into the different size rear crossmembers. Seems like I saw those measurements printed somewhere??? I have an entire room of early Ford info, unfortunately I had a stroke and it's all new to me again.

If the frame rail reinforcing plates are similar to the gauge of frame,11 gauge, it would be close to 1/4" shorter. Just mock up the rear crossmember with your rails using bolts through the rivet holes. The rear frame horns on each side of the tank need to be 40" outside to outside. If it's less than that, you might have the "late" rear crossmember.
