i have the old style spindle with key axle and want to upgrade to disk brakes but have not been able to find a set that just bolts on. So now i am looking to just replace these axles with ones that have the whole hub with studs built in so that i can purchase a disk brake kit to install. but i am lost and dont even know where to start. ive watched some videos of how to pull the axles and think i may be able to get them out, but im not sure what new axles to buy and what disk brake kit to purchase and install. any help would be greatly appreciated. If there is a disk brake kit that can somehow bolt straight on with these axles that would be awsome... but i have no clue how i would bolt the rim on... this part is confusing me.
