1970 K20 Restoration

[D.PASSMORE]

Red was original on 1970 3/4T.
On the front axle - 71/72 Dana 44, its a direct bolt in. The only difference is ensure you have the same gear ratio and you will need to swap the brake proportioning valve to a drum / disk set-up. Any used axle would need to be gone through and rebuilt. Check with this guy, not to far from you, he has a lot of 67-72 parts - Tom, http://67-72chevytrucks.com/vboard/member.php?u=966

T case is a rockwell 220, you can tell by the shifter position in the middle. Parts are very scarce and not as durable as a NP 205. NP 205 is still the king of t-cases. To replace, it is a direct bolt in, but you will need the shifter / adapter/mount / connecting shaft spline sleeve and maybe drive shaft yoke. Also, the 4x4 high hump cover for a 71/72 truck. sounds like a alot but it isnt that hard. just do your reserch on this site.
