Make a sleewing for the part in the bottom where the axel is wider as its used for standing the bering on and when you switch to swift berings they are bigger and therfor you need a bigger platform for them.

 

If you dont whant to make a hole new mounting for the brakepads and use the existing one from the swift you need to make a spacer so that you have a spacer with both the minis 3 bolts to atatch it to the arm and the swifts 4 bolts to atatch the brakepads holder to it.

 

You need to sleewe the axel to be abel to adapt the bigger berings from the swift if you decide to use ther hub.

 

A new washer, not at all necesery as the mini axel is so slighly smaler but if you like.

 

A spacer betwene the hub and disk as when you fit the first spacer to hold the brakepads holder you move the pads out with the thiknes of the spacer and ther for you need one underneth the disk to compensate for the move.

And its also probably necesery if you dont whant the swift bolt patern as the hub is week inbetwen the original bolts.

 

The thiknes of the 2 spacers you can also use insted of doing a extra spacer to adust the with betwene the wheels to get what you have in the front.

 

So if you like the boltpatern as it is then you only need to do a new mounting for the pads, the 2 sleewings and you are home.

 

And if you dont like the swift patern you need to make the 2 spacers and 2 sleewings.

So we made new drawings and changed the rubber dome that is the suspention for a spring and some aluminium mountings for it to save space and therefor we culd mount the holder for the brakepads directly on the rearweelarm wich made the weelbase unchanged.

 

Thees last 4 pictures is taken with my telephone so they arent that good but i havent had eny time to take eny, so you have to make do with thees for time beeing and i will also uploade some more text in a while.
