Adjust and Vectorize simple diagram

Hi

I need someone to make very simple adjustments to the attached diagram, as follows:

Make the doors narrower so the wide rail at the bottom will fit underneath.

Make the roof not as wide so the rails fit in

The diagram must look normal (a car diagram) with defined lines.

I will then need it to be vectored with proper defined lines so it can be printed on A4 with no loss of quality.

I will then need a number put in each part, which I will confirm on assigning the job.

Effectively it is a combination of the two diagrams, any questions please do not hesitate to contact me.

I anticipate this to be a very quick job if you know you way around illustrator.

Kind regards

Sam
