    I have an 84 K5. I'm thinking about doing a 14 bolt swap and want to know what needs to be changed. Is the breaking system compatible? I know the driveshaft needs to be different but anything else?

    The driveshaft will be fine you just need a hybred U joint..I forget the # but do a search on it. Everythign else is a bolt in as long as the axle is 3/4 ton. depending on year parking brake brackets may need to be fabricated or purchaced

    You can use your driveshaft, just use the napa u-joint 447 it converts 1/2 ton to 3/4 ton. If you get a 14 bolt from an 81 and later you can just bolt the e brake lines right up.

    the drive shaft will stay the same you will need to put in a new u joint,part #447 at napa. the braking part will depend on what backing plates you have on the 14ff

    Just the rear u joint. I have the conversion joint in mine and it is Napa part #447. Also the e brake will work if it is a Burban or 1 ton 14ff with the e brake cables that the passenger side crosses over the pumpkin to the driver side.

    Another thing you will need are new u bolts and the spring plates unless they're comming with the axle.

    To put it in a 91 you will need the same stuff. Also if the axle comes from a 1 ton you need to move the spring pads and shock mounts.

    yes they'll work...... if you use a cutting torch to get them red-hot and re-radiused to compensate for the larger axletube... i had to do this 'cause my lift was for the 1/2 ton.... kinda tweaky, but it got the job done...

    whats the difference between a 14ff on a 34/ ton and a 14ff on a 1 ton.....does a 14ff look the same as a 14sf?

    The ff will have hubs sticking through the center of the wheel and the sf won't.

    I got my 15" 8lug wheels locally for 280 installed. I know ToyBoxOffroad is running a special right now for 55 a piece.

    You can get 15" 8 lug rims from alot of places. I got mine from Summit Racing and they cost me just over $200 for 4 of them to my door.
