Acorn nuts?
If so, RB Motion #1455 .075" work nicely.
I also just got real metal ones from Ben (Class A Resin) with a set of Peterbilt wheels. They are even more realistic as lug nut covers, but I'm not sure if he sells them seperately.
I placed two orders last year, and I don't remember being unhappy with the timeframe, but I'm not sure exactly how long it took. They make great stuff, and I'm planning on ordering again as soon as they have the latest releases ready on their website.
I ordered directly from CTM's website. It was pretty easy. Just download the excel order form and type in it to fill it out, save it to your computer then send it as an attachment to CTM in an email. They send you a Paypal payment request, and there you go. Really prompt service and shipping. The photo etched items are of the absolute best quality and detail.
Just came across a 1/87 scale 1977 Country Squire wagon on Shapeways by a guy named rapidpro. Wonder if it could be printed in 1/25? Then, it could be used to convert & cast a wagon from Missing Link...
Hmmm, maybe I'm just dreaming again.
Ya know KJ, I'd think there'd be a market for a 3406e/C15 conversion kit.
Valve cover, timing cover, etc. to convert the old 3406 into a modern version "E". You could call it a yellow engine "E" upgrade kit.
Thanks for the info, I may go with the Lonestar to start, probably get both kits eventually. CTM makes a etched detail set for both, and someone makes a flame mask for the Lonestar, I'll have to track that down.
