I think you've posted in the wrong area, but either way.
Darren would be best to answer this as he did it, without a conversion kit.
Not 100% sure but biggest things (from memory);
You need to mate the stagea bonnet skeleton/hinges to a 34 bonnet skin
Need to replace nose cone
Cost/effort involved unless you have a 34 sitting there you wanna hack up and time/skills, Id go Masa kit. 6k delivered from memory.
