Something to be aware of when getting patch panels.

The metal is likely to be thinner. This isn't some evil ploy by part makers to take advantage of poor 'ol diesel owners. It is due to the use of soft tooling / hydroforming in probably an underpowered stamping press.

The body lines might not be as crisp or shaped exactly as original. This is due to soft tooling / hydroforming , variations in factory cars. It two factory panels were slightly different, you probably would not notice it, cut them in half and swap halves and there could be a noticeable difference.

An example is when I spliced the front and rear of a factory bolt on rear fender on a early 70's VW Type 3. Using the car as a jig, the top and bottom lined up but the body line was slightly off between the two.

For a low production car, all the panels are probably coming from the same or a handfull of makers. My question to the sellers would be: Is the panel made from Galvaneal or painted? ( If painted you will need to remove the paint and start from bare steel. )
