I have been working on backdate of Trumpy P-38 L to a P-38 G. The front canopy wind screen is rounded on the early version G, and the kit supplied front canopy is flat. Will either need to modify and polish the L front wind screen (doable if enough plastic is there?), or an aftermarket canopy will need to be found. I am certain this problem has been faced before. Has any one successfully modified kit part, or am I stuck finding aftermarket part. Thanks for help...Bob.
