update, I had some time to finish welding the main part of the frame, minus some gussets and brackets.
i have the frame under the xj now, its all aligned i'm just waiting for my body mounts to arrive so i can attach it to the body.
also mocked up the rear axle with the tires on it to see the fitment.
next update I hope to have both axles in and ready to start my 4-link suspention.
