That's not a Ford rear axle and I don't believe the car is a Ford either.How about this radically bobbed T Racer. The brakes appear to be off of something else. This must have been meant for short sprints but I would think those seats would get too your back going to and from the track......But these guys back then were tough as nails......
It's a Chevrolet 490 rear axle.
Herm...... Could you share some more photos and details of it with us?? Thanks, T-H
