Buy complete door cards, man.
Any auto upholstery guy worth a damn will charge you more than they are worth.
I always keep tabs on CraigsList, and just recently picked up a complete
brown interior for a mk2: Door cards, handles, a, b & c pillar trim, rear seat, etc..
for FREE!!
It came from a 85k mile garage queen 4 dr Golf...
Keep the faith, and look to buy.
even up to like $200, and you should be well under the cheapest upholstery shop.
