Yamaha Forks on f650gs

So got myself a Dakar and doing some upgrades and TLC over time and when money is available. I have been following a thread on advrider.com about putting Yamaha yz450 forks on f650gs. I have all the parts except for custom axle and caliper bracket. I can buy it from overseas but it costs R6000 which is not in budget.

So has anyone locally done this conversion all I need is the measurements of those parts. I tried getting them from 2 guys on advrider.com but they won't give them. Let me know thanks.
