I'm putting the finishing touches on my boxed model A chassis. I prefer the look of the plain front frame horns without a spreaderbar. Does the front spreaderbar really make a noticeable difference in driving characterists or chassis strength?
Even with an unboxed frame I couldn't see it providing any benefit since it's so close to the front crossmember.
I have run boxed, and unboxed Model A frames. A spreader, bolted in, or welded in, has no effect on the frames function at all. IMO a spreader on a Model A adds absolutely nothing at all in the appearance department either. If you are running a race car, you need a place to mount a race tank. If you are running a street car, you don't need the tank and everyone, who matters, knows it's phony. Opinion from an old Model A drag racer.
Where will you hang your number plate with out one ? As stated above, Model A s didn't have a spreader bar. (and is cosmetic only on '32 fords, although they may have been used to 'spread' the chassis rails while the crossmembers were fitted. I made my rear one extra heavy to act as a bumper and to prevent damage to petrol tank in case of a rear collision.
I have seen them on Model As in pics from way back. It's not that folks didn't fab them, they did, the question was if they served a purpose, structurally - which they don't.
