My 71 K20 Cummins swap

I started this project back in 2013 when I purchased a 71 K20 from a local plumber/electrician for the sum of $2000. They were originally asking $4000 for it, but the seals between the transmission and tansfer case were out and they were wanting to be rid of it. It had a 350/350 set up from the factory and a service box that dated back into the 50's. it had carried that loaded service box around most of its life, so the springs and bushings were pretty well shot.My first order of business was to fix the leaking seals and put new springs under it. I put Rough Country 2.5 inch springs in the front and ordered factory 7 leaf replacements from SD truck springs for the back.
Here are some pictures of it when i bought it.
