Complete yzf front end swap

[fullthrottle]

Managed to pick up a complete front end off a 2006 yz450f for $250 including wheel brake m/c plastics t/clamps.

Just to confirm if I change the head stem bearings and get a steering stop sorted I can fit the complete front end??

Forks will be revalved and new springs, what spring rate should I look at? Im 70kg no gear.

What is the measurements of the bearing I need?

Where will this leave me in terms of fork/axle offset compared to stock?

Thanks for any help
