Hello all, I’m trying to figure out my Frankenstein Jeep as it’s registered as a 63’ CJ5 But I am learning, thanks to others on another post I had, that at least some of it is a M38-a1. I’m trying to figure out if the entire tub, frame, etc. is a M38 or anything else I can to understand what i have and what direction to take it as I source other parts, and looks. What differences, measurements, etc. can I look for to investigate? Thanks!
