looks really really great!

shockwaves dont make great bags for ultra slammed trucks because they only have about 5" of usable stroke, even with the geometry of the a arms that will only work out to about 7-8 inches of lift total. make sure that your 6-7" ride height isnt topping out or close to topping out your shockwave, its usually closer to 4" for half travel on a shockwave (with the front end geometry added) so most setups either set the truck up to lay out OFF the ground to get more ride height, or move to a different bag type. if you try to ride around topped out the shockwave shock will break. I have seen it happen in person.

those lincolns are 5 on 4.25 stock but you can make them 5 on 4.5 with cobra IRS parts if I remember right. you can also use the cobra center section to get a LSD, the mark viii used electronic limited slip, applied the brake on the spinning wheel to make the other spin.

good luck, great start! thanks for all the high res pictures!
