I recently started building models of all 7-slat jeeps but not able to find everything in the 1/25 scale I have chosen. So, I have to make some of the versions. Right now I am getting ready to start an M38A1 but they don't exist as a kit so have to modify a CJ5. Remember, these are only 6" long so the 24v electric system difference is irrelevent! But other than windshield are there any differences I need to do?
