Re: 1968 K20 New Project

For a stock truck, no oversized tires or hp. That front end is... ok.


I would recommend simply to pull the whole unit and replace it with a 10 bolt or Dana 44 front end with factory disc's. Get a small hub version for cheaper hub parts. With a 12 valve I would recommend running a Dana 60 front from a 77-91 Won Ton.

The drum brakes in the stock closed knuckle front end will not be up to the task with the heavy Cummins in it. If you do plan on pulling that t-case lever into 4x4, the 10 bolt/Dana 44 axle will not hold up.

Just find a Dana 60 if you really plan on putting a cummins in.
It will bolt in. You might want to change your brake master cylinder and proportion block. And swap out the Eaton rear diff for a more common 14bff.


I will finish mine some day.
