Sorry not to answer this one before but I was not near computer for almost two weeks. As for this matter I am preparing full list of things that will have to be considered when you are makeing this kit. It will be in bullet points with all the "problematic" issues (and trust me this window thing is not the worse
)
All in all we should all be aware that Reji makes nice subjects in a little "for experienced modelers" models and the only thing you should realy take care of is that you are prepared for every chalange. As for the trim (well not the trim but part of doors) you are right you have a problem with that. Mine didn't have that problem but it had one of the intakes on the hood missing (well not missing but it looked like resin residue and as a matter affact it wasn't) so I made a new one. Right front winndow was something similar to yours but it was easily fixed with putty. The most important thing is to fit vacuforms before you paint the body because there is a lot of work on them.
But like I said you will find the complete list once the model is finished.
I would only add that you should take resin as it is and make it the best way you can, this process (of makeing resin models) is not the same as the plastic, they are what they are, hand made master peaces and it is only up to you will it be good enough at the end so take your time ant a lot of sanding paper and putty and you will make it at the end.
