Creating a formula to find the first specific number of characters from a description

Please see attachment.

In column E theres a whole list of descriptions, I need an advanced forumla to create a sku for them based on the following requirements.

The first part will remain PCCWT-

The second bit will take the first 3 letters of the manufacturer (ie for audi it will be pccwt-aud-)

The third bit will take the first 2 letters of the next word (model) (ie for an a audi A4 it will be PCCWT-AUD-A4-)

Then the first 2 letters of a description (ie there could be an audi a4 estate or audi a4 saloon, there could be 3 door hatchback or 5 door hatchhback - I need to try and find a way to dot his so that it works the same for these skus as well as one other systems.

ie PCCWT-AUD-A4-EST)

Then it will take the first four numbers of the year so if its 1995- 2000 it will be PCCWT-AUD-A4-EST-1995-) - this will be tricky as some models have numbers so maybe theres a way that it will only find the first 4 numbers that are together without a space or -

Then it will take the shade which will be either 5%, 20%, 35%, 50% or 70% (it will add these witout the % so PCCWT-AUD_A4-EST-1995-05 (note if its 5% its changed to 05 so its always 2 numbers)

If it says full kit, rear kit or front klit then it will add FR (front) FU (full) RE (rear)

So the final will be PCCWT-AUD-A4-EST-1995-05-FR

Ive got a few channels that I need these skus adding to so if theres anyone on here who can do this work for me (as I know it maybe siomething that someone has to actually get there hands on to make something that works Im happy to subcontract the work out (obviously its gonna take a while for me to do these manually but I need to make sure the skus are made the same on 2 different channels.

Is there a way you can separate column E out into the different fields you list above?
