Im gonna fit fenders up to cj3b frame. Gonna have to remove a lil material from left fender where it interfears with shock mount. First pic shows where left fender is contacting rear of front shock mount bracket. Right side is really alright no issues except for aft of fender there is a hole to mount rear of fender to frame , hole is missing on cj3b frame. Second pic shows shock in lower left corner of pic the shock mount for the cj2a , which is different then cj3b .
