While browsing last few hours searching for bearings 
I actually completed this table that contains all parts from Guessworks full kit for A+ gearbox and diff.
Their most complete package contains only one idler gear bearing and doesn't contain 1st, 2nd and 3rd gear bearing. Parts that they offer in their kit are not the cheapest one, on contrary....although with TMF+ discount prices there and in Minispares are very similar....
