1928 - 1929 lower cowl question.
 

Hello,
Are all lower firewalls interchangeable on 1928 and 1929 ford body styles?

Looking for a 1928 ford roadster lower firewall and wondered if they were all the same. Thanks.

The early ones are different from later 1928 & 29. The edge where the lower cowl lacing is attached is more recessed on the later ones to allow easy installation of the lacing.

Thank you.

The firewalls on Fordors and Cabriolets are significantly different than others (have two pieces to the main/lower section below gas tank).

I have no direct experience with the very early 28's, but as far as the differences in the cowl welting location, I was under the impression that the width of the lower cowl panel itself (not the firewall) accounted for the additional width in that area.

Seem to recall that the location of the starter rod hole was the only difference between the early '28 and later 1928-29 firewalls.

The whole cowl is different on the subcontract cars like the Fordor & Cabby.

This link has photos of the early flat face firewall and the late type with the recessed edges.

FWIW, here's a picture of a cowl assembly I disassembled a couple of years ago. No doubt an all original assembly. I believe it shows the earlier style firewall was assembled with the later style cowl panels that have the wider area for attaching the welt. No doubt originated in a transition period as the left brace on the assembly also had an original block off plate over the hole where an early left hand parking brake would have been mounted. Besides having three rivets to attach the cowl panels to the firewall there was also several spot welds. Seems like mix and match wasn't a problem with Ford.
