VNB4T conversion 8 to 10 ''


I would like to make conversion 8 to 10 '' in front wheel of my VNB4T from '64 (I have px engine on rear). Does wheel rim (SPAQ or Mauro Pascoli) fits to Vespa 125 VNB4T and can be used as conversion rim? 

Somebody use it like this and can share photo?

I would like to be sure that it fits to VNB4T because on photos of this rim the place for drum looks much more wide than 8'' drum. Also in internet I found that everybody use bajaj fork or conversion kit (changing axle) and nobody use this rim...

Another question is if this rim have influence on track offset?

Thanks for your help! 

Best Regards,
