will the body mounts on my 85 cj 7 frame line up with the 90 yj body im trying to swap over ive roughly meashured it and it seems close but aint shure about the one under the role bar    (im keepin the cj grill well whole front end )  

You're going the wrong way. The YJ frame is far superior to a CJ frame...

Just cut them off and put them where you want them. And give it a little "body lift" at the same time.  

i was wondering why you'd wanna keep the cj frame as well  

the drivetrain is supped up and has new suspension but the floor boards are rusted threw as well as most of the cab and doors and my yj cab is mint but other than that its *** and the motor mounts, trany skid plate holes seem diffrent (its my first rebuild) tryin to keep it simple  

and i can weld cuzz thats whut i do at work but i aint got one at my parints houce whare im doin the build
