This thread about Kadee parts is good.
IMHO, the most needed detail part from Kadee are 18" bracket
grabs!!! Even though they are delrin, they are look great, and a
good alterative to filing the Intermountain ones down to respectable
proportions (or doing other surgeries to get a wire horizontal).
Of course, the delicate Detail Associates 22" ones aren't bad. Maybe
someone knows why they did those instead of 18" ones...
