Thanks for the feedback. It's much appreciated.
Mopar-D - I haven't decided on a color yet. I think it will be dictated by what images I can get for the outside of the van. Right now it might be black or white.
Foxer - Thanks for the hinge advice. I'm going to try to use the resin doors since they have the stock Dodge script. I have a rough idea of what I want to do, along a similar line to what you did. And yes, I saw your build you started in 2011. I won't feel rushed.
Nitrozilla - I'll look for that PE guy in Canada, thanks. He could come in handy.
rsxse240 - Actually, the glazing putty was the 2-part stuff, and it came right off. I have aspirations of sculpting some parts, not necessarily for this build, so I'll keep the Tamiya putty in mind (I was thinking Sculpy, the kind the military modelers use).
crowe-t - I've had so-so luck with CA glue, including a couple of early ideas on this body, but I did what you suggested. And I think it works! See the images below. Medium CA with an accelerator applied. More CA to fill the gaps. And it stood up to shaping and sanding!
Tom - I've seen your build & it looks great. This being a resin body, I expected and encountered areas of more and less thickness. The front doors were the hardest around the wheel well, it being curved and having a lot of over-flow resin from the extra plastic used to cover the gap to the chassis. Aside from that, once I poked a hole, I could then switch to a #11 saw blade and carefully finish the line. I bet a PE blade and some patience would work wonders. The thickness in the door panel itself was taken care of by scraping away the unnecessary resin a little bit at a time and matching up the kit interior door panel as a guide. It's close, and I'll likely need to fill the gaps with something later. You are correct in that replicating those nice hinges in a reasonable scale will be a trick.
I really want to build out the interior of this van. Being in my early 40's, I wasn't really conscious in the late 70's and early 80's of anything outside of my Matchboxes and Hot Wheels. So I went on line and picked up a couple of reference materials. Neither book has a dedicated chapter on the subject, but apparently, judging by the photographs and illustrations, a bikini-clad woman is an essential accessory.
