Here
(M38 build) is the build I used their original M606 kit on about a year ago. I backdated their M606 to an M38 with low hood. It was a great kit to build. The only issue I ran into is that the frame was about 2mm too long for the body. I think this is due to them using the AFV Club M38A1 frame. The M38A1 was slightly longer than an M606. I cut the frame just in front of the rear axle. It is an easy fix, just match up the front shock cutouts on the CJ3B body and the frame, then shortened the frame as needed, about 2mm. The rest went together without issues.
