A few years ago I picked up a Model T frame from a local guy. After reviewing this site, I'm 90% sure it was produced in 1924 (4-hole quadrant, no holes for cast running board brackets, no front fender extensions).
The rear cross member that came with the frame was bolted on a long time ago. No rivets so can't be sure it came from this frame. Had to use a torch this weekend to get them all loose. This cross member is in bad shape with cut off ends, distorted spring channel and grossly over-sized spring bolt hole. The two tab extensions that are on the bottom of each frame rail are cut and the square bracket inside the x-member channel is gone. I suspect this was used as trailer or something at one time.
So I picked up another cross member that was advertised as pre-26. I noticed the replacement cross member doesn't have the holes (highlighted in yellow) for the spare tire bracket. Does that narrow down the body styles it would have come from? Were the spare tire bracket holes drilled on the line or was the lack of holes a feature of a specific frame production year(s)?
Just curious, I can of course drill the holes depending on the body style I may get but would like to learn more about the frame features.
Thanks for the help, I'm still waiting for Bruce McCalley's CD to arrive. (Kind of surprised the spell checker has an issue with Bruce's last name ???)

Pre 1919 frames were likely not drilled for spare tire carrier.
