Carb spacer plate (NOS)

[Turbodave]

I picked up a few of the aluminum spacer plates that go under the carb that have been set up with Nitrous jets going into the secondary bore. Both the fuel and N20 ports are on the side of the plate that faces the firewall. The plates look like a factory part otherwise. I was just curious if the factory plates already had holes on the backside that just served a different purpose, or if these are a unique piece. I only have one carb motor around and it came out of an 83 Scamp GT that had a NOS nitrous kit on it at one time so of course it's got the same plate as what I've got only rubber caps have been put over the jets (system was removed before I got the truck). I'll probably end up selling these parts, but want to know how unique they are before I go setting a price.


Thanks

I believe they did have a port on the backside of the plate, but if I remember correctly it was either for the PCV hose or for the brake booster vacuum line.
