I recently took out my gas tank of my 87 yj to repair and found that the rear frame is rusted bad by the shackle mounts, more so on the right side.

I found these repair kits

I'm wondering if wraping the existing frame will just cause the replacement parts to rust being in contact with rust to begin with?

I'm also wondering about putting a shackle mount on the underside of the frame to give it a little lift. Since I'm new to this not sure what problems could arise by doing it.

Thanks,

Mike

Moving the shackle mount to the bottom of the frame is common.

My solution to the rust problem is below

 I like that and will see what I can come up with close to that.

I see you are from Merrill, I get up that way and shoot handgun silhouettes at the  Medford Rifle Club. In winter I'm ne of there calling coyotes, even had one run into my back this year   I have inlaws ne of Antigo and also hunt with a friend in the Nicolet.
