GROUP 26-01---FRAME ASSEMBLY ( Up to Ser. # 199079)--model CJ2A

Frame Assembly (use 648644)  PART No. 640218

Frame Assembly (use 648646) (Same as frame 640218 except 647009 bell crank bracket replaces 640208 to accommodate inverted bell crank)

 

I have a little issue here with The #'s 640218 and # 640208. This appears a mistake?

 

I put these two frames side by side, each side and pic,ed them together. There are alot of pics ...but notice the extra holes on the '47 frame compared to the '45. These look to be stock on the '47.  Take special notice to the sleaved hole in the front. Both '47 & '45 have the sleave but  '45 is worn out to the end of the sleave. There are alot of hole differences. Most looked original. Another interesting difference is the bracket for the rear muffler holder.. it is opposite in these. And then there was no rear muffler in the '45?  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I'm sure after a time I will get it... have patience and make sure you more experianced guys cover my a$$.  I appreciate it greatly.

 

#21s frame should not have holes for exhuast hanger in k-member. My frame numbers 10030 thru 17173 (6 of them) do not have holes. My frames after #23281 all have exhaust hanger holes... including #29258 (MB frame). Check out Group 31-01 (exhuast). The exhaust system changes from side exit to rear exit at serial #18638. I would expect the frames to change somehere around then as well, but I don't see any notation in any of the parts manuals to reflect the change in the frame to accomodate this.  

 

 

 Could it be possible get some pics of the rear bumpers? Thanks a lot!
