This is an Original NOS set of starter brushes. These are listed as fitting the GMC G85 version of the 2 1/2 ton military truck. There are quite a few different applications the 2 1/2 ton GMC truck chassis such as the CCKW, GMC Bomb Truck, DUKW, and several others. They all used the inline six 270 motors. This little brush kit is for the six volt starter on these motors. I am positive this will cross over to many other starter applications including the 1 1/2 ton Chevrolet. I am not a GMC or Chevy parts guy so you can sort this one out. The part numbers are provided. Now for the sale stuff…These came in a small wooden crate packed bulk. They are all in the plastic like bricks but some have an envelope but most don’t. The paper dry rotted and fell a part. The little plastic like coating is very easy to break apart and get the brushes out. Sorry no choice of packaging but if you order more than one we will do our best to try to get an envelope in with the order but no guarantees on supply.
