Re: 1970 K20 drums to disc conversion

I’d start looking thru craigslist in your area for a 3/4 or 1 ton front axle with 4:10s. Keep in mind that if you swap both with the tire size your running I wouldn’t stray to far numerically lower from 4:10 other wise it’s gonna turn into a dog off the line pretty quick. Also with swapping the rear end if you go to a 73-87 rear your limited to 1 ton single rear wheel(not 3/4 ton) being mostly bolt in.(need to change one shock mount) 1/2,3/4, 1 ton dually will all need perches and shock mounts moved.
