Sweet deal on tires is going to cost me I just know it!

[budman k20]

I need help! I got a great deal on 315/75/16 tires on 16 x 10” wide alum wheels. I measured the OD to be real close to 34” when on my 72 K20. I did not measure the back spacing yet but it looked close to 4” the wheel just covers the disk in front. Here is where it is going to cost me. I already purchased new front springs and shocks with a 2” lift. I have not put them on yet but I jacked up the frame 2” to see how the tire clearance would be. The short answer is no way will that be enough lift. Kept jacking until I had about 4” lift (tire about to come off the ground) and even that looked marginal. My next thought was since I’m taking the body off the frame to put a 1-2” body lift on it. To get the minimum 4” lift our official chart recommends for 35” tires! So I searched for body lift kits and did not find any 2” kits? I don’t do any serious off road stuff I mainly pull trailers with my truck and when I do go off road I pretty much just drive fire roads. I have never driven or rode in a lifted truck and I don’t really want it any higher than necessary to run these tires. What are the main issues to lifting the body? I assume longer brake lines to the MC and fuel lines. How do you move the bumpers what do you do with the steering column? Is it going to simpler to just bite the bullet and put a 4” lift under it and not lift the body? As you can see I have a lot of questions. My sweet deal really complicated my life right now!
