Having looked into this quiet a bit (as just did custom lights on my "project car" ... making a v2 as we speak) ... you'd have to use either 33 or 32 lights.
I've measured up 34 lights and the outta area of the stagea lights are too small to fit anything bigger than the 33. Even then they'll need to be placed so they sit slightly out of the normal light area (not flush to standard stagea rear lights). You could use 34 lights, but they're not going to sit well (as in flush with sides of car) on the car and stick out a bit
The inners are a piece of cake to do.
My only other concern using 33/32 lights is reverse/indicators, but nothing a bit of bog, fibreglass & some extended wiring couldn't fix l guess.
Somethign like this l was going to do (inc french boxing the no. plate down lower) .... but l cbf'd and would rather spend the time and energy on my other car. But if u do do it def. post up pics.
