I retained my stock '28 Tudor's firewall but deleted some of the "warts" and widened the stock recess. What *was* the stock recess can now accomodate a big Hemi V8, but it still retains the stock steering column opening and cowl legs.
If you want something smooth with no bumps, here’s my old 31 roadster, “ hotrodA” I cut back the stock firewall even with the lip that retains the hood lace. I cut a piece of 16 ga. exactly matching the outline of the lip edge and carefully welded it to the edge. I cut out where the recess for the distributor needed to go and cut off one end of a Detroit Diesel valve cover that fit in to the cutout. This gave me a neat lip to define the opening and a compound curved recess.
@1941g506 Might want to edit the title. I was getting ready to show my firewall as well. Maybe "Homemade Bodies using Stock Model A Cowls"....
There was a thread on years years ago, something like "So You Started With A Cowl" or something like that. I have tried a few times to find it but with no luck.

Here's one I started a few years ago. 30/31 cabriolet cowl and a 30/31 sedan back section with unknown 30's doors to finish the body. That's as far as I got for now but hopefully I'll get back on it soon. Itll never be pretty but i think the stubby little sedan made out of junk will be cool.
I’m using just the gas tank for my speedster project https://www.jalopyjournal.com/forum/threads/a-v8-speedster-‘sat-nite-spcl’.1270422/ Reminds me I need to update my build thread
I started this cowl using a 30? Briggs or Murry model A cowl ,no fire wall, for a single seater T build. Just removed the fire wall and gas tank then sliced it down the center then over lap the two pieces, clamped it to the frame rails and loosely clamped the center then just started sliding the two halves together until I got the width and arch that I wanted and tacked it together....the side panels were just card board in this stage of mock up.
