Phil,
I found that the shorty panels (about 8-10" tall) fit better than the ones I got initially from Jim Carter. They were shaped closer to what fit well at the front corner with the toe panel on the replacement floor pieces I got (the right and left ones that include the toe board). I was far enough down the road on the ones I bought initially that I decided not to use the shorty ones and sold them to another Stovebolter. In my investigation of the issue, I saw the full panels from Dynacorn
link that looked like it would be a good fit, but don't have direct experience with that. Here's some pics for comparison of the two different inside cowl panels I had. I beat the longer ones into submission as I didn't want to deal with another weld joint part way up. If your rust isn't too high on the panels, the shorty ones should probably work for you. Expect to do some customizing them to fit in any case. That's just the way it goes.
