Downhill ski bindings

Downhill ski bindings

My daughter has an old set of downhill skis. I am wondering if any of you guys work at a ski shop or know anything about remounting ski bindings.

She need to get new boots (size 6-7 womens) because she has outgrown her old ones (size 5 womens). Will the old bindings work or do I need to get new bindings. The existing ones are Tyrolia 520, DIN 0.5 - 4.5 (whatever that means).

What will happen to the existing holes from the old bindings? How do you cover them up if the new mounting holes are different?

Any ski expert here? Help please.

I don't know weather you will have to get new bindings or not.. but the mounting holes should be predrilled and threaded with various locations for diffrent sizes/ types of bindings... just like a snowboard

since her feet got bigger, has she outgrown her skies?

Her feet got bigger. Her skis are 130cm. She is 53" 70 lbs. The existing bindings are adjusted to the max length. I was thinking of moving the front and back of the bindings farther apart since it is 2 pcs. The thing that I am worried about is I will be leaving holes on the skis from the existing bindings. I'm not sure if this is going to be a problem. I did not want to spend anymore $ on winter gear (but I'll spent $ on cars, he-he-he) so I was considering just buying her new (used) boots and adjust the existing hardware.
