Hi Mike just to help people answer your question.
I believe you are asking is the gearbox in a felicia 1.9 diesel car the same size, fitment, ratios etc as the 1.9d pickup.
Regardless of whether the pickup is Technically a VW or a Skoda .
I have a x car gearbox in my 1.9d Volkswagen pickup which I much prefer to call my Skoda in disguise
