Hello Mike,
Post a link to some pictures if you can. Are the inner and outer side cowl needing patch panels? If they are I have done that and highly suggest you save the inner to outer piece, they call it the hockey stick, because the replacement ones are no where close to the originals. You will most likely find you will have to work the inner pieces too.
Good luck with your restoration. I just lifted the cab off my 1948 two ton.
