Need help with homemade armor

Hey guys, I'm flying to Kansas next week to visit my grandparents farm. They have a metal shop and I would really like to make some armor for my xj. I really want to make diff guard covers for my dana 30 and chry 8.25 and maybe some rock sliders.
Does anyone have any plans or templates I could use to build these?

here are some pics I found that look good enough to get the job done, I'm not worried about looks, just function.


I don't have any measurements or plans or templates for anything, and I can't bring my XJ with me so anything you guys have would be very helpful.
Thanks,
Dan

A stock diff cover would make a decent template. It would be easier to buy a diff cover kit or just the diff ring. Try here - http://www.ruffstuffspecialties.com....html?osCsid=9423fea73adb25ec1addbce4c2a549a4


Rock rails are simple. The pinch seam measurement is not included because it can vary from Jeep to Jeep.

.

Good Info there

Yep, its about just like what I did for mine except i used 3/16" for evferything and 1x3 from the frame to the rail
