The only major change you would have to make for a non gulf war RAF buccaneer would be the wing tips. You need the longer ones which are also in the kit ( I'm away from my stash so can't check but I'm almost 100% certain) that and aerial fits and what you hang under the wings. Oh and if its an early RAF version be sure to use the flatter bomb door.
There are some guys on here that actually worked on them so they are better placed to confirm/ correct that. There are some differences if you want to do a South African or Royal Navy version which is down to fuel tanks , pylons and weapon fits.
Bottom line you are good to go for any RAF version but check your references.
