[Healeys] Pedal box mods

[e-wilkins at cox.net (Eric (Rick) Wilkins)]

I have looked around but haven't seen how much modification the pedal  
box of a left hand drive car needs to make three carbs fit. The two  
setups I have would be three SU or three Weber DCOE on the shorter  
Australian manifold.

Can someone here help me with drawings, photos or a good description  
of what's involved?

Thanks,
