Hey Jim, I got the tail lights installed last night. No real drama to report, everything fits okay, just really tedious and extreme caution using the x-acto knife.
I used the Traxxas Blazer body to make templates by tracing the cut-outs onto a small piece of paper, taping the templates to the Axial Blazer and using it to guide the knife and score the lexan. Then I drilled a couple pilot holes near the scores so I could begin to separate the area to be removed into segments and break the lexan. Finally, I spent an hour or so whittling the hole to the proper size and making fine adjustments to get the lights in their proper place.
For the markers, when I painted the body I had intended to use the supplied stickers then scratch build some small light buckets to illuminate them. So before painting, I applied rectangular paint masks that formed side marker windows in the lexan. However, now that I have the Traxxas marker assemblies, I could cut these windows out similar to the Traxxas body but I think I might try a shortcut; drilling only the mounting holes for the two screw bosses (plus one small hole for the key post which insures that the led will align with the top lens and not the bottom one) omitting the cutout and see if this will be sufficient. I will try this approach with one marker and insert an led to gauge the results. If it looks okay, I'll do the same for the other three. If not, then I'll follow the same method as for the tail lights (use cutting templates).
Either way, I'll let y'all know how everything went. If anyone is interested in cutout templates for this mod, I could scan mine and attach them as jpeg images that you can print to scale. Just let me know... TTYL
