Adding to garage with modified parts

[Humpty's Revenge]

I'm trying to add a manual gearbox conversion to my modification list but it won't let me because I cant state the product as it doesn't have a manual gearbox in product?

EDIT:- There is quite a few things I cant add!!

cant you just add a new product?

I'm not sure bud? I can put anything that's not listed as unbranded! Which I think I might do

Just click the "not listed" link above the two white boxes, this pops open a new window allowing you to put in new stuff.
