180calipers To 1.9 Hubs..what Bolts?

[camgti 56]

Kinda of a confusing question here,

 

Ive got 180 Calipers and am not sure what bolts to use to mount them onto the 1.9 hubs. I originally had 1.6 hubs and calipers and bought the 1.9 hubs bare and want to now fit the 180 calpiers. Question is, it looks like the bolts are to long for the 180 calipers as the 1.6 has a longer tunnell section for the bolt to go through on the caliper and then into the hub. What is the bolt length i need?

 

If anyone can follow this please help!
