30/31 Roadster Sub Rail Dimensions

[goleafsgo_12]

Hi guys,

I'm looking for sub rail dimensions for a 30/31 roadster. The rails are reproduction and have no holes, and the car is in pieces. I need to get this thing together and want to start with square rails! Any info would help, Thanks.

Dale(eeyore) and I are going through this search for info on the 28/9 roadster subrails and other things. Seems like no one is willing to share information. Had a few good replies to Dales thread on lower quarters, but it seems tough to get guys to give up pictures or what info they have.

On your roadster, do you have the rear body crossmember part of the subframe?

I am building a 29 type roadster body from parts I've collected plus the Brookville parts where I have to. All I can suggest is to start piecing it to align it with a good straight Model A frame & new body blocks. I'm fortunate in the fact that I also have a coupe body to do some of the sub-frame comparison. I'll be using screw fasteners to start with and rivets to follow after everything is fitted & aligned. I have enough key pieces to locate a few original holes but the rest will have to be drilled to the frame holes and by guess work/comparison. I figure if I get something off fit, I'll likely know it by the time I get most of it together and I can weld it up & re-drill as required.

Also, if you haven't already, check out Vince Falter's site. He has excellent drawings of a 30 coupe body disassembly/reassembly under Body Details~Model A.

I also used info from here

and here

I seem to recall that some of the Wescott dims are not accurate but the have helped me in the re-assembly of my 30 deluxe roadster.

My roadster is in winter storage so I can't get them real easy but if there is a critical dimension you are looking for PM me and I can try to get it for you.

Thanks for the help, I didn't have much luck going through searches either. I do have the rear body cross member as well as the correct cowl for the car.. I think what I'll have to do is order a floor kit, set the rails in the cowl and try to install the rear member. From there I should be able to figure out where the cross rails go. Is there a bracket to tie the rear most body cross member into the sub rails? It seems that the rails are flat, but the cross member has vertical mounts. What ties the vertical mounts into the flat rails?

The rear most body crossmember should have 2 integral brackets on each side to attach it to the sides of the subframe - I think they were originally riveted together. Maybe post a picture of your cross piece so we can tell if it's all there as should be.

I've posted a picture of my cross bar in the model A section under, if somebody could let me know what brackets I am missing on the ends that would be great.
